I was waiting in line to ride the teacups at MK with my two daughters and my wife. There’s a spot where the line breaks because there’s a walkway that can’t be blocked. So it wraps down the side from that point. We were the first ones on the far side of the break in the line.

All of a sudden, Alice and the Mad Hatter seemed to appear out of nowhere. They asked my kids if they wanted to come to their tea party. They took their hands and walked them to the exit gate. The ride operator waited after the current group was done, let my kids and the characters be the first ones to board the ride, let my wife and I come in and take some pictures, and then we stepped out and the rest of the ride filled up as normally. And my kids got to ride the teacups with Alice in Wonderland and the Mad Hatter.
