Hi, Sharon!
One of the best things about a Disney Cruise is that there are many onboard activities and events scheduled for every member of the family -- and I mean that they've thought of
everyone! The last time I was on board a Disney ship this summer, I paid particular attention to that "gap" group of college-aged kids. Studying my daily
Personal Navigator, I noticed that there were several meet ups such as lunch at particular locations on the ship as well as dance parties at the adult clubs. They also met for card games, movies, ping pong, swims in the adult pool or coffee at Cove Cafe, and since they are still "kids," they also had video game contests in the sports bar, too!
Since the youth activities spaces are for kids under 18, young adults (ages 18-20) are welcome in the adult lounges, nightclubs and bars. (Of course, they just can't consume alcohol.) They also can make reservations at the adult-only dining locations such as
Palo or Remy and book spa treatments, too. They are welcome at the adult beach at Castaway Cay -- Serenity Bay. There are even super active
Port Adventures exclusively for adults and designed for the adventurous types like young adults usually are. If you can write back and tell me your ship and itinerary, I can make even more custom suggestions for you and your traveling party.
Thanks for stopping by, and I hope you have a wonderful day and a magical vacation. Bon voyage!
