Yes, quite viscious for young (& old!). My 5 year old enjoyed being at the very edges of it & watching the excitement. My 9 & 10 year old are still talking about the bruises & scrapes from it. I was actually rather concerned after seeing a few kids in too far & getting hurt. Overall loved it all there though. But I would recommend BB over it if I had to choose only 1.
It was a freezing cold day when we were at BB and warm & sunny day we were at TL, but the 5 year old LOVED the kiddie area much more at BB than TL. DD's 13, 10, 9 all preferred BB. YMMV though. Theming at BB cuter for us Northerners in Florida, I thought. But Shark Pool is only at TL, if that's a draw for you.
