Right. I was just referencing the most popular slides as "e-ticket", sorry for the confusion. Yes, you just get in line. At BB, Summit Plummet and Slush Gusher are the two big ones, they're right next to each other. Slush Gusher is a lot of fun, but beware you can get a little bit airborne over the last slope. It's a ride that goes down, levels out, drops again, levels again, drops again. You build pretty decent speed and at the last drop you can do a bit of a jump. It's fun, just be ready for it. At TL, Humunga Kowabunga is the big slide. I suppose you could call Crushin' Gusher an e-ticket ride. It's kind of a roller coaster water slide, where strong water will push your raft up an incline, then you go flying down the next drop.
The "second tier" slides are the ones that don't get as crowded. Both parks have mat slides, inner tube slides and body slides. They both have lazy rivers. The one at BB flows a little quicker, though by no means fast. The one at TL is so slow you can get stuck at times and have to you your hands to paddle forward a bit.
