You should post this on the general boards, not trip reports. You will get an answer more quickly.
My boys are college age. But the kids clubs are fantastic. Go to the movies. The theatre is beautiful and if you don’t like the movie just leave, no pressure. See the beautiful stage shows.
I think you are on the Dream, so do the Mid Ship Detective Game.
Castaway Cay, if the weather is good and water temperature swimmable, then get in the water. Rents some tubes. They also have a great kids club area.
Pelican Plunge is fun. Make sure you make time for a tasty lunch. Ice cream machines are right there on the island, yummy.
You can take a bike ride on CC too.
Nassau we were there twice, once after a storm and did not get off the ship. Second, time we all went snorkeling. Lots of fun.
The general boards have a lot of info. Good luck.
