Sunset and DJ beats on the water. That’s the core of this Mykonos boat party: a double-decker cruise where the day turns into nightlife, with an open bar and a swim stop near Rhenia Island. You’ll still get the classic Mykonos coastline views, only this time you’re watching them from deck level instead of from a crowded club floor.

I like two things a lot: the unlimited open bar (including flavored mojitos, beer, and sangría) and the Rhenia Island swim stop with inflatables and snorkeling gear. One watch-out: the vibe can skew very party-forward, so if you want something calmer, you may not love the crowd energy and drink-heavy atmosphere.

Key highlights

• Double-decker boat party with deck space for views when you want a break from dancing
• Live DJ sets + unlimited open bar kept going through the evening cruise
• Swim and snorkel option at Rhenia Island, with inflatables and gear provided
• Sunset plus evening coastline lights, best enjoyed with a drink in hand
• Up to 150 people onboard, which can mean a lively, tight feel in peak moments

First impression: what you’re actually buying for $114.52

This is a 4-hour Mykonos party at sea, starting at 5:00 pm from Delos Tours in Mykonos Old Port. For $114.52 per person, you’re paying for a specific bundle: boat time, DJ music, an unlimited bar, and water activities with gear included. If you were planning to spend similar money on cocktails at beach clubs plus a transport plan plus entry fees, this can start looking like a straight-value choice.

The “boat party” label is real here. This isn’t a quiet sunset cruise. You’ll be on a moving party platform, with a DJ driving the mood and most of the group leaning into the evening. That’s fun if it matches your travel style. It’s less fun if you came to Mykonos for scenic calm.

The 5 pm timing: how the night shapes up on the water

Starting at 5:00 pm is smart. It gives you two distinct vibes in one outing:

• Early cruise time when you can still see the coastline clearly and settle in without rushing
• Sunset turning into night when the lights along Mykonos start to pop and the DJ energy ramps up

You’ll want to plan your day so you’re not sprinting from one place to another. I’d treat this as a main event. If you try to add a full club run right before boarding, you’ll end up tired and slightly out of sync with the mood on board.

Also, since the experience requires good weather, the timing matters even more. If the conditions aren’t right, the operator may switch dates or refund. So have a flexible plan for that night if you can.

The double-decker boat: views, space, and the reality of a big group

Because it’s double-decker, you get options. When the music is too loud or you want photos without heads in the frame, moving up or down the boat can help. Deck space also matters for a swim stop later—boarding and hanging near the water areas feels different from being stuck mid-boat.

With a maximum of 150 travelers, it can feel crowded at peak moments: bar lines, DJ zone movement, and the “everyone trying to get sun or photos at the same time” window. My practical advice: choose a spot early and stick with it. Then re-position closer to the swim stop and sunset if you want better angles.

If you hate clutter and tight movement, this setup may feel like a floating version of a busy nightlife strip. If you’re okay with that tradeoff in exchange for the open-air party atmosphere, it works.

Open bar value: what’s included and how to pace yourself

This is one of the strongest selling points. Your bar includes premium brands, with specifically listed options like flavored mojitos, beer, and sangría, plus bottled water and soda/pop. In plain terms: you’re not just buying access to the party—you’re buying the drinks that fuel it.

Here’s how to think about value. Mykonos is famous for nightlife, and drinks on the island add up fast. Even if you only drink a couple of times, having a true all-you-will-actually-use bar can lower your overall cost of the night. If you’re the type who orders two cocktails and then switches to something non-alcoholic, this can still make financial sense.

Now the consideration: with unlimited alcohol onboard, pace is everything. One negative theme from people who didn’t like the experience was the party crowd and heavy drinking vibe. So if you’re going with friends and you want a good time, set your own rhythm: water after drinks, and don’t treat the swim stop like a sprint.

The Rhenia Island swim stop: inflatables and snorkeling basics

The highlight on the water side is the swim stop near Rhenia Island. You’ll have a chance to cool off in the sea, and you can choose your comfort level:

• Inflatables for lounging and floating
• Snorkeling gear if you want to look around underwater
• Or just enjoy the water break while others snorkel

What I like about this structure is that it gives you options without forcing a single activity. You can be the person who swims for 20 minutes and then goes back to deck life. Or you can spend longer in the water if that’s your plan.

The practical part: moving from party mode to water mode can be a bit chaotic if you wait until the last minute. If you want snorkeling time, get in early. If you just want to cool off, you’ll still enjoy it more if you’re not rushing with everyone else.

One caution I’ll flag: some people described the experience as focused more on the party than on the island swimming itself. That means your water time may feel like a “stop within the party” rather than the main attraction. If your top priority is hours of snorkeling, you might end up wanting more.

Sunset and coastline lights: why this cruise feels more Mykonos than a club

Mykonos at night is visual. You see it from alleys, from balconies, and from the harbor—yet the best “wow” moments often happen when you’re in motion, with the shoreline unfolding behind you.

Here, you get that during the sunset-to-night transition. As the sun goes down, you’ll watch the lights along the coastline come alive, while the DJ keeps the energy up. This is the part that feels like you got something different, not just a repeat of club nightlife.

Bring a mindset shift. Instead of thinking of it as downtime between drinks, think of it as a guided change of scenery. The boat gives you a moving viewpoint, and that alone makes the sunset feel more special than a one-spot beach sunset.

The crowd: when it’s a dream and when it’s not

This is the area where you need to be honest with yourself. Some negative feedback you’ll want to consider is the teen-party vibe people experienced: a group energy that skewed young, with people described as getting very drunk and taking over seating on the boat.

That doesn’t automatically mean it will be like that every night. But it does mean you should expect a lively crowd. If you’re traveling with a group that wants calm conversation, you may feel out of place. If you’re in the 18–25 party zone (or you just like a high-energy nightlife environment), it may feel perfect.

Also note one more point that came up in negative feedback: some people felt the food aspect was basically minimal. The tour includes drinks and the sea time, but reports suggested that if any food is offered, it can be very basic (like fruit such as watermelon and banana). If you need a solid meal, plan to eat before you arrive.

Getting there and what to bring (so you’re not scrambling)

Your meeting point is Delos Tours, Mykonos Old Port (Μύκονος 846 00, Greece). The activity ends back at the meeting point. That means you don’t need to worry about a complicated drop-off plan—just make sure you can get back to Old Port after 4 hours.

Pack like you’re doing both a party and a water activity:

• A swimsuit or quick-dry layer under what you’ll wear on deck
• Something easy to step in and out of for the swim stop
• Sunscreen (yes, even later in the summer light), plus sunglasses
• A small bag you can keep with you on the boat

Because it’s a boat setting, wind can change how cold you feel after sunset. A light layer can save you if you run hot during the day and cool down once night hits.

Price and logistics: is this good value or just a splurge?

Let’s do the honest math in travel terms. You’re paying $114.52 for a 4-hour party with:

• Unlimited open bar (alcoholic + soda + water)
• DJ
• Inflatable and snorkeling gear for a swim stop near Rhenia Island
• Sunset and a moving view of coastline lights

Value depends on your drinking style and your appetite for nightlife. If you’d otherwise spend a chunk on cocktails and a club entry ticket, this can feel like you’re buying the full package. If you don’t drink much and you’re mostly there for the water, you might find the price steep compared to a simpler boat option.

One more logistics angle: it’s booked about 30 days in advance on average, which suggests it sells enough that you may not want to wait until the last minute if you’re set on going. That said, you should also read your confirmation and voucher terms carefully after booking, since some people reported confusion about changes or refunds after purchase. The general policy on cancellations is time-based, but real-world experience can depend on what the final voucher states.

Who should book this boat party (and who should skip it)

Book it if you want:

• A DJ-driven night on the water instead of another club line
• A drink included experience where you can pace yourself
• A real swim stop with inflatables and snorkeling gear provided
• A convenient, 5 pm start that helps you structure your evening

Consider skipping (or at least think twice) if you want:

• A quiet, scenic cruise where conversation is easy
• Plenty of time for serious snorkeling
• A crowd that’s mostly older, calmer, or less party-focused

This is best for people who like a social atmosphere and don’t mind that “party boat” means the energy can be intense.

Should you book this Mykonos boat party with swimming?

My take: if your goal is a fun, loud Mykonos night with DJ music, an open bar, and a quick swim near Rhenia Island, this is a strong match. The mix of sunset views + water time + included drinks is exactly the kind of all-in experience that saves decision-making during a short trip.

But don’t book on autopilot. Pay attention to what kind of energy you want onboard. If you’re sensitive to a younger party vibe, or if you care more about calm swimming than nightlife, look for a different style of cruise. And whatever your travel style, eat beforehand so you’re not relying on minimal onboard food.

If you want a lively night that feels different from standing in a club, this boat party can deliver that—just go in with your eyes open.
