In my opinion - TL is the best!
We were there on 8/1 with kids 1 - 9 yrs old. We "camped" out in the kiddie section. I stayed there most of the day with the girls, chasing 1yo and keeping an eye on 4yo - who did kiddie water slide and kiddie raft ride.
My husband took the boys to the shark reef first thing. He also did Humuga Kowabunga with 8yo. All the boys (6,8,&9) did the regular water slides and a bit in the wave pool. Everyones favorite was the lazy river. We could even take baby on it.
We got there at 9:15, planned on leaving at 1:00, but we were having so much fun, we stayed until 5:30. It was a great day!
Good luck and have fun!
