I would do BB as they have the preteen area which my DDs (5, 7)loved. There is a tube slide, a body slide, ice berg walking and one of those hang slide thingies where you hold on with your hands and then let go before you hit the end and a small area where you can just swim. They also have a great family raft ride. Much better then TL. The wave pool is not as large but we spent the majority of time at the preteen area. The lazy rivers are about the same.
