Hi Patrick!
It sounds like you are getting ready for a Walt Disney World Resort vacation with little ones and you have picked a fantastic time to visit! You will be able to enjoy the
Epcot International Flower & Garden Festival,
Minnie & Mickey's Surprise Celebration and so much more during your trip. Plus, you will be able to experience
Lightning McQueen's Racing Academy, which is a brand-new attraction opening March 31, 2019, where you can experience Lightning McQueen's state-of-the-art racing simulator and meet Cruz Ramirez following the attraction!
Pixar Play Zone is an awesome event currently available for kids 4-12 years old, where they will enjoy a fun evening filled with games, a tasty dinner and a visit with some favorite Pixar Characters. When Pixar Play Zone was announced last year, it was announced as a pilot program. You are correct that reservations are currently open for Pixar Play Zone through the end of March. No official announcements have been made about the future of Pixar Play Zone, so I recommend that you keep an eye on the
Disney Parks Blog for announcements about offerings available for your little ones during your upcoming vacation!
Let us know if we can provide you additional help as you continue finalizing your plans. T-T-F-N, ta ta for now!
