Hi, Vandy!
Disney Cruise Line ensures that no matter what your "demographic," you have a phenomenal time aboard. In short, the answer is YES. There is, daily, at least one activity dedicated specifically for single adults.
You'll find a
Singles' Mingle at night in Diversions lounge, for example, and other evening fun in the other 18+ nightclubs.
During the day, single adults may have their own trivia game tourney, or an excursion group in a port of call, or a wine tasting. Your nightly Personal Navigator will describe in detail the events of the next day, broken out by age group and interest type.
You'll find that most cruisers on board are receptive and friendly, and you'll have no trouble finding lots of fun companions on your voyage. Magic happens on board Disney ships; you'll find, I hope, friends and memories to last a lifetime,
Bon voyage!
See you later, celebrator,
