Hey there, Casey!
Thank you for visiting planDisney with your great question about Walt Disney World Resort water parks.
Casey, the reason you cannot
make a Disney Park Pass theme park reservation online for a Walt Disney World Resort water park, is because park reservations are not required for the water parks. Park reservations are only required to enter the four Walt Disney World Resort theme parks.
Please keep in mind that water park reservation requirements are subject to change at any time. I always encourage Guests to bookmark and
review the experience updates page often. This wonderful resource is chock-full of information on the phased reopening of Walt Disney World Resort.
If you have any additional questions, please visit planDisney again. We are always hEAR to help you!
With a Sprinkling of Pixie Dust,
