Hey there, hi there, Marisa! Welcome, and thank you so very much for your question.
Disney Cruise Line makes things like this easy peasy, so I'm glad to be able to help you. You can register for any of the Youth Clubs, like
Disney's Oceaneer Club and
Disney's Oceaneer Lab right when you do your
online check-in 30 days prior to sailing. And there are no worries if you don't get around to it prior to sailing. The crew from the youth clubs will be available both at the port and at an open house hosted on the first day of your sailing, and you can register the kids then.
I highly recommend, even if you registered in advance, that the grown-ups pop on over to the open house that first day. It's one of the few times they let adults in to explore the amazing kids' facilities, and it definitely gives you confidence when you meet the staff and see how cool the spaces are.
And since you'll probably now have a lot of free time, with the kids falling in love with the kids' clubs, look into making yourself a reservation at the
spa or salon. You can get a massage, have your hair done, enjoy a facial, or just relax in the Rainforest Room.
I hope you have an amazing time on your upcoming high seas adventure, Marisa!
