The bookings for Singles Cruises increase each year, as do the listings on Cruisemates' Singles Cruise Calendar.  According to a March 2006 Mintel report on Singles and Travel (Attitudes and Behavior), singles represent 41 percent of the U.S. population of approximately 121 million people. The study also indicated that a third of all singles travel alone. So it is no wonder there is such demand for organized solo cruising. {mosmodule module=insert sponsored links} As the numbers of solo bookings grow, the emphasis on sex and booze has been replaced by singles just wanting to enjoy a vacation with other singles. As cruise lines started offering incentives and lower prices for large groups, it encouraged families to travel together, but discouraged solo cruisers when they had to pay a hefty singles supplement to occupy a cabin by themselves. However, organized singles cruising solved that problem by offering cabin-mate matching.
