I THINK I'm getting a snow day tomorrow, and I'm so excited, this will be the first of the year! Well, technically, we had one right after Christmas, but I already had the day off, so it didn't count! We're supposed to get 10-20 inches throughout CT!
Anyway, about the water parks...they are fun, but like you, I'm not much of a water park person. I did both BB and TL in one day, I think we were finished with both by 1. We went to BB first, right when it opened, stayed a couple hours, then went to TL and did what we wanted to do there, and then left.
I liked TL much better than BB...BB is all about the big, thrill slides, and honestly, they are not that thrilling! They're annoying!

I went down Summit Plummit and it was over before I knew what was happening, and at the end of the slide, all the water that is at the bottom kind of hurts when it's pushing against you...and you have to stand up with a huge wedgie, which is really uncomfortable!
TL is a lot prettier, more tropical, and they have fun water slides. Crush N Gusher is awesome, but a word of advice-lift your butt up when you go over the things that propel you uphill, they hurt!

They have 3 regular old water slides that you just slide down that have twists and turns that are fun! And the wave pool is awesome for people who like wave pools...which I don't, but Brandon loved it! And the lazy river is fun...but I got bored with it kind of fast! I can't spend a lot of time in a pool, which is what I felt like I was doing in the lazy river!
Hope that helps! They are a lot of fun but you definitely don't need more than a couple hours at each one!
