My son was 10 last year when we went and we are going again this year. He had a great time & I'm sure your children will too. There are so many different types of things to do, it just depends what he enjoys. My son loved Bingo, he enjoyed all the shows (we all laughed a lot at some of the smaller shows like Family Karaoke, etc.). He swam with his little brother at the Mickey pool some and enjoyed the slide there too. He also got a kick out of some of the little things like ordering free room service, shuffle board tournament, vegetable race, etc. He didn't spend much time at the Oceaneers Lab, but a lot of kids really enjoyed it. He also had a great time on the excursions bcs they offered good beach time. I know they will love it...not to worry. Have a great time.
