Thank you for the replies.
Unfortunately, Epcot is not in our plans for this trip. We're only going to MK this time since we're venturing off WDW property for some different adventures. Thankfully, dd has gotten Belle's autograph several times on past trips since she won't be able to this time.
So sad....and very odd that you can't get her signature even though so many new fantasyland elements focus directly on her story.
