Hi Will! Welcome to planDisney!
Thanks for bringing your planning question to us! I know coordinating a visit to the Walt Disney World Resort can be overwhelming, especially since things are updated often, but that's why we're here! We love to help Guests navigate their way around planning a vacation at the Most Magical Place on Earth.
All four of the Walt Disney World theme parks are open and operating daily at this time. They will be open on May 28, 2021, but looking at the
Theme Park Reservation Availability calendar for that date, it looks like all four theme parks are at full capacity and there are not any Disney Park Pass reservations available.
Occasionally, more
Disney Park Pass reservations will become available as other Guests' plans change, so keep checking! If more reservations open up, you will want to purchase your
Walt Disney World theme park tickets AND make a Disney Park Pass reservation right away since both are required for theme park entry. If you are unable to snag a theme park reservation, consider a day of exploring
Disney Springs or a day at
Disney's Blizzard Beach Water Park instead!
I hope you can visit soon, Will! Please let us know if you have any other questions.
Tabitha
