Hello, Kati!
Oh, boy! You are 48 days away from a fantastic vacation at Walt Disney World! You must be so excited!
Both
Disney's Typhoon Lagoon and
Blizzard Beach are fantastic water parks, but each one has an attraction or two which is different from the other. If you'd like to snorkel with sharks and schools of colorful fish or ride the water coaster Crush 'n' Gusher, head to TL. However, if you'd like the challenge of Summit Plummet or Toboggan Racers, you'll want to spend the day at BB.
There are dedicated fans of both water parks, to be sure, but my family really prefers Blizzard Beach. Check out the links above for more information about the differences between the two parks' attractions so that you can be sure to chose the one that's right for you and your husband. Either way, you're in for a fabulous day at a Walt Disney World water park!
Be sure to send additional questions as you think of them, too, be they about your water park choice or even your free dining options! I love to help!
