Haven't done BB, but I loved TL and it seems like a great place for the younger set. The children's area looked so fun, and it has age requirements so your youngest can't get run over. There are also two little slides off to the side of the wave pool that are both tame enough and "wild enough" for your oldest and possibly your youngest. They would even like the family raft ride - short and some splashes but no drownings!! The wave pool and sand are awesome and the kids meals came in a bucket with shovel that my girls put to great use. Have fun at Disney!!
