Yes!!!!
I can tell you this, Blizzard beach felt like much more walking than typhoon lagoon. However, BB does have the ski lift to get you up to a certain point so you bypass a lot of the stairs. BUT there's also a line for that. And once you go down a slide, you gotta go back up to get to the other slides, naturally. They have the tallest slide in the world there (at least since I last checked). It goes straight down!
The awesome thing about TL is the Crush N Gusher. It's a coaster slide! And SO MUCH FUN! Also you can snorkle through this little pond sized thing with sharks, fish, stingrays (they are all toward the bottom) and that was really neat. But it was REALLY COLD -- they said they have to keep it that way for the sea creatures.
I'm just not sure how it will be in Nov/December. I hope it will not be too cool.
If you have any specific questions about the water parks, I'm an open book.
