We have 4 kids and have been to both water parks. They both have a nice area for young kids who are not strong swimmers with small slides, fountains, shallow pools, sand, ect. Both parks also have a nice lazy river that we always enjoy as a family. If they are brave enough, both parks have wave pools, but the waves can get pretty big so you will have to hold onto them. We were at BB in early October and I think we have decided it is our favorite. They have a good "tween" area. If your oldest is a good swimmer he/she may enjoy it. It is the "ski patrol training school" that you always see on the Disney DVDs and videos. It has medium sized slides, but when you land in the pool you DO have to swim to the side. My DD6 had no problem with anything in the area, and my DD11 and DS9 loved it too. DH and DD13 took off for the mega-slides. The water parks are moderately crowded anytime it is warm. It was mid 80's when we were there and crowds were manageable. Weekends in the summer are the worst as locals come too. HTH....Lacee
