We he never been to either but I hvae to say TL tempts me more than BB. Although DH would prob disagree with me.......infact that is probably the reason why we have never been to a water park....we can never decide on which one to go to!
TL always seems so relaxing but at the same time has so many cool things to do. BB seems a little 'peh' to me.
Hopefully we will do them soon enough and then I can be of more help!
