We alternate every year ! Both have plus & minus.
Small children - I think BB !
Young kids - I think BB !
The rest - I think either one depending on what you like.....
TL plus - awesome wave pool, shark reef, more tropical & adult decoration
BB plus - feels like more slides or maybe they just moved faster, the way it is laid out it doesn't feel as crowded as TL even at peak attendance, skylift up to top, "seemed" like more food options, mini-golf is right there if interested
