Welcome to the Disney Parks Moms Panel, Elizabeth!
I'm so glad you stopped by. So, you're off to meet Hiro's personal healthcare companion? How wonderful! I frequently travel with high school students to Epcot and many of them report that Baymax was their favorite character of the entire trip. He gives the most magnificent hugs.
I checked several Wednesdays in late August and it appears that
Baymax will be greeting guests in Future World until 9 pm most nights. Be sure to pick up a Times Guide as you enter
Epcot to verify those hours, but it looks like you should have no trouble meeting Baymax on the evening you plan to
dine at Epcot. Be sure to have your camera ready so you can capture your son getting the biggest hug from this truly memorable character.
Let us know if you have any additional planning questions as your trip approaches. I'd love to help you make your son's first trip to Walt Disney World magical.
Wishing you many magical memories,
Jill
