Great report! I love Typhoon Lagoon. Blizzard Beach is great but, if given the choice, I always go with TL. I love the theming (it makes me feel like I'm on Castaway Cay from Disney Cruise Line) and, this sounds weird, but the layout is so much simpler and easy to get around than BB. It's a circle, so you can just pick a spot and start making your way around. There's plenty to do but not so much that you stress out trying to do everything like a checklist. Don't get me wrong, I also enjoy BB (especially the theming) but it just seems busier, crazier, and harder to navigate.
And, yeah, the water in that Shark Lagoon is COLD!
