Depending on how many are in your party, the upgrade to waterparks & more is worth it and then you can do both parks. We would rather do waterparks & more than hop because we are going in September. Last year, we did waterparks in the morning to afternoon, lunched at the lodge and chilled until evening when we went to the parks. My boys love, love, love the water so it is a must that we do both parks. I like the setup of BB and they have one of the fastest, highest body slides. I was clocked at 60 mph!! We love the view from the top of the ski lift and that you don't have to climb to get to the top. The turn around time is quick. They, too, have a wave pool but it is smaller but the wave is HUGE!!!!!. Some of my fondest memories are relaxing in the tube at BB. On the other hand, we LOVE TF also! It seems a bit more crowded but the kid's section is very, very nice with the waterguns and such (I think that was TF) correct me if I am wrong. They seem to have quite a few water slides but mostly its all about the WAVEPOOL! Huge and spacious. Perhaps the biggest thing that pushed me over to the BB side was the Ski Patrol Training Camp for the 12 - teens. It's not so babyish like the little kids area but a bit tamer. This is especially for the poster who said that her DS doesn't like the tall slides. It's a cool place for preteen and teens (and adults) to stay cool and have some fun too. We love both but I think I like BB the best.
