Aboard Carnival's Valor, single people in their 20s and 30s can sail the Western Caribbean for seven nights in early April and visit Grand Cayman, Honduras' Isla Roatan, Belize and Cozumel, with the start/end point being Miami. The schedule is action-packed for the young clientele, so a person will never be bored on or off this boat. Carnival is said to be the best cruise line for the younger single crowd.
For eight nights, you can immerse yourself in Croatian culture, music and cuisine, while stopping at fascinating old villages and admiring the grand beauty of their coast and the Adriatic Sea. This trip is geared towards the 35 and under scene, so it's perfect for travelers interested in touring Eastern Europe's sights with other young singles instead of among the older set, which is typically more common on European cruises. This cruise is offered by the Singles Travel Company, and comes with lots of extras just for booking with them.
For three days aboard Carnival's Imagination ship, singles can have one big Halloween celebration at sea. This is a Caribbean cruise that goes round-trip from Miami to Nassau, Bahamas. Highlights include a costume party, late-night buffet, happy hours, many on-board activities, entertainment and amenities. Escapade Cruises sells this route, and also caters specifically to singles travel in general.
Contiki Vacations, which is geared to travelers in the 18- to 35-year-old range, has three European cruises on its trip roster, all of which are in the Greek Islands, and combined with land tours as well. The time spans are nine days, 13 days, and a whopping 35 days. To be clear, Contiki's tours are not advertised as being solely for singles, but given the age range and the hip, fun vibe they project, they are a great company for young singles to consider when planning a cruise or other adventure.
This cruise is specifically for the young single men out there who are interested in older women. The International Cougar Cruise is a three-night outing on Carnival's Elation ship, which travels from San Diego to Ensenada, Mexico, and back in early December. "Cubs" or "cubbies" might be able to find someone special on board to share the holidays with, or else at least enjoy the festive journey with them. This cruise is another offered by the Singles Travel Company.
