Hello, Michelle,
Isn't it so much fun to think your trip to Walt Disney World is just a few months away? To help with your planning, both of the
water parks are heated year-round. However, the attraction
Shark Reef at Disney's Typhoon Lagoon Water Park is not, which can catch you off guard when you enter the water.
As for the crowds, your trip is likely overlapping many schools' spring breaks, so that will increase the number of guests. I find when we go during the summer that if we arrive when it opens, we can enjoy many of the attractions with little to no wait in the morning then we switch to the wave pools and lazy rivers as it gets more crowded as those hold the crowds well.
If we can help with any further questions, please let us know. We are happy to help! -
