Welcome back to planDisney, Mary Beth! I'm so glad to hear that you have plans to visit Walt Disney World Resort in the first week of April. There is always excited energy in the air when new attractions are opening, and I just know that there are going to be tons of Disney fans eagerly anticipating the return of
Happily Ever After!
Although it will be a popular day at
Magic Kingdom Park, I don't think that the opening of
TRON Lightcycle / Run will cause any hiccups in your plan. Suspension of park hopping due to capacity is very rare, and I can think of maybe only one or two days in the past few years where that has happened. That said, Happily Ever After is extremely popular and guests are very excited for it to return so I recommend getting to Magic Kingdom Park as early as possible after park hopping opens up so you can guarantee yourself a spot inside the Theme Park. I'm willing to be that it will be a busy night on Main Street, U.S.A.!
Although we haven't heard anything about a dessert party for Happily Ever After quite yet, I think that
Madame Leota's crystal ball would say that the outlook is favorable. I recommend that you keep an eye on the
Disney Parks Blog, which will be the first place you'll hear any breaking news about new entertainment offerings.
Have a magical day, Mary Beth!
Jessica
