Hi Bonnie!
I'm not 100% sure which America Interactive Greeting you are referring to, but I can provide you with information on the attractions for America in which you may be referring.
I visited Walt Disney World this weekend and had the pleasure of attending the International Epcot Flower and Garden Festival. If you are referring to the show that occurs in the America Gardens Theatre, you can check the show schedule for times and performances at wdwwent dot com. You will be able to see the performances planned for the time during your visit. The show was extremely popular and I saw guests line up well ahead of the performance to attend.
The Flower and Garden Festival ends on May 19, so if you are referring to the special demonstrations, food and DIY HGTV performances, those will not still be occuring on May 26.
If you are referring to the American Adventure Show held in the America Pavillion in the World Showcase at Epcot, those shows occur daily and you can check the
American Adventure page for showtimes.
I hope you have a magical visit!
Magically,
Stacy
