We did the Wonder when my girls were 7 and 9 and then this year they were 8 and 10. They loved making Flubber, they made volcanos (my kids favorite), organized games, video games, movie theater trips, game room trips, lunch trips, Goofy came in and played games with them, more arts and crafts, karaoke, trivia and prizes, pizza pajama party, science experiments and more. They were never bored! They stayed together in the 8-10 year old group both cruises. Have fun! They will love it.
