6 Best Party Cruise Ships

The quintessential cool party cruise, adults-only sailings on Virgin's Scarlet Lady promise legendary musical entertainment. Artists, like Mark Ronson and Diplo, are expected to join some of the voyages starting in 2020, which include stops at Virgin's private island resort, Bimini. There's an onboard tattoo studio, drag queen brunch and "Scarlet Night," which is billed as the "party to end all parties" (bring your red attire).

Signature drinks: Try the Yasss Queen, a Champagne cocktail with citrus bitters, hibiscus and ginger; or the Rizzle Dizzle CBD cocktail with gin, elderflower and black pepper.

Featuring a 17-degree-Fahrenheit ice bar, Norwegian Breakaway features some of the coolest drinking establishments at sea. Other fun spaces include Syd Norman's Pour House (including live rock band performances), Jimmy Buffett's Margaritaville at Seaand Bliss Ultra Lounge, with a spacious, glassy dance floor just begging for you to showcase your best moves. Don your best white duds, grab a light stick and head to the ship's legendary adults-only White Hot Party known as H2Glow at Spice H2O, a space just for grown-ups both day and night.

Signature drink: The Rebellious Fish: passion fruit liqueur, orange vodka, orange liqueur, orange juice and sparkling wine, garnished with fresh berries.

Grand Celebration, along with sister Grand Classica, offers two-night Bahamas itineraries throughout the week, year-round -- the perfect weekend getaway. These cruises tend to appeal to younger travelers -- 20- and 30-somethings -- plus Florida locals. Take a long weekend and extend your stay with an all-inclusive package at a resort (including unlimited food, drink and resort activities) for a mid-cruise land-based stay.

Both ships offer a half-dozen bars that stay open until the wee hours, slinging tropical drinks like specialty mojitos, plus nightclubs that start the party early, from 6 p.m. with dance-friendly tunes. The line is also known for booking big musical acts throughout the year such as the Marshall Tucker Band, KT Tunstall and Tito Puente Jr. -- check the entertainment schedule in advance.

Signature drinks: The Encore, a vodka-based cocktail with lime juice, basil, ginger and cucumber; acai caipirinhas; and lychee martinis.

Carnival's Fantasy-class ships are legendary for their free-wheeling, fun-loving atmosphere, so much so that some Southern California locals dub Carnival Imagination the "booze cruise." Value-priced, shorter sailings earn this ship plenty of repeat customers among young people looking to escape the grind of LA life. Adult-themed comedy shows and an adults-only sun deck are draws, plus Imagination's 10 bars and lounges (including the super popular Alchemy Bar) that stay open late so that people on the shorter itinerary can make the most of their long weekend getaway.

Signature drinks: ThirstyFrog Red (Carnival's private label beer); Ting mojito.

Though Galveston-based cruises don't have the hard-partying reputation of those on the coasts, if a party is what you're looking for, you'll find it on a short-but-sweet jaunt on Enchantment of the Seas. Eight bars and lounges, plus nine pools and hot tubs (including an adults-only Solarium), are among some of the amenities to help you unwind. If you're feeling a bit more active, take your partner for a spin salsa dancing at Boleros, bounce on the bungee trampolines or get soaked on the Splash Deck. Late-night dance parties often take place on the pool deck under the stars.

Signature drink: Lava Flow, Royal Caribbean's signature pina colada streaked with strawberry and rum.

You already love to brunch so hard, so why not do the at-sea version, with Carnival's Seaday Brunch, filled with all your favorite brunch bites and drinks? Carnival Fantasy, the oldest ship in Carnival's fleet, is still going strong on short cruises. It features the RedFrog Rum Bar, with rum drinks available by the pitcher, and giant onstage battles of Connect 4 and Yahtzee. Mobile-style Mardi Gras parties (complete with beads) are also occasionally on the agenda, and late-night dancing at Electricity Nightclub gets started at 11 p.m.

Signature drinks: Order a round of beer or margaritas for your group at RedFrog Rum Bar with the 101-ounce "The Frog Likes to Share" tube, pitchers or yards.
