Whether some time as a couple is on tap or you just need to relax as an adult without kids in tow, cruises offer a range of opportunities for grown-ups only. From all-adult decks to itineraries for the 21 and over set, check out cruises that pamper and cater to adult interests.

Cruises With Fewer Children

When all-adult itineraries seem limited, there are other ways to get on board with adults only. Book luxury cruises such as Silversea Cruises. Cruises geared toward adult interests such as opera, or longer in duration like Oceania's 18-night Panama Canal Cruise or 36 Night World Cruises are less likely to have children on board. Educational cruises on small ships featuring expert-led tours, onboard enrichment classes and activities geared toward adults such as wine tastings and lectures are also a good bet. Book on smaller ships with limited children's facilities, and plan your excursion when school is in session.

All-Adult Options on a Carnival Cruise

Carnival's Serenity Adult-Only Retreat isn't its own ship, but it does provide an area that is exclusively for the 21 and over set on 10 ships departing from Florida to cruises that include the Caribbean, Bermuda, Bahamas, Cuba and the Panama Canal. Set sail from ports that include Tampa, Miami, Port Canaveral, Jacksonville and Fort Lauderdale. Kick back on a lounge for two, take a nap in a hammock or enjoy signature cocktails.

The Cloud 9 Spa on select Carnival Cruises are for 18 and over. Enjoy a thermal suite where you can relax in the dry heat of the Tepidarium or Laconium or breath in moisture in steam baths. For a special treat, book a journey on the Carnival Breeze out of Port Canaveral to enjoy a Thalassotherapy Pool that bubbles away tension with seawater and massaging jets.

Enjoy an all-adult outing on a Caribbean cruise on the Secrets Adult All-Inclusive Beach Adventure in Montego Bay, Jamaica. The 5.5-hour excursion lets you enjoy the sun and sand while savoring exotic fruits, fresh water coconuts or cuisine like jerked chicken at one of the buffets, restaurants and lounges. The experience includes unlimited premium alcohol, use of watersports equipment like Hobie cats, kayaks and snorkeling gear, live entertainment and partially-heated pools.

Finding an All-Adult Cruise

Adult cruises fall into the category of lifestyle cruises, put together by a cruise and event producer who charter a cruise ship for the event. Singles cruises, senior cruises and couples cruises are just three kinds of adult-only itineraries you might find on adult-only cruises. Take a Bliss Cruise geared toward couples aged 21 and older and you'll be on board with open-minded couples that might include swingers, nudists, exhibitionists, and voyeurs. The cruise takes place on the Celebrity Silhouette which has a lawn on its upper deck with outdoor grills. Sail from Florida ports on cruises heading to Jamaica, Mexico, Belize or the Caribbean. Find more adult cruising options out of Florida through travel agencies specializing in adult-only travel like SinglesCruise.com or Erotica Adult Travel.
