Sorry to take so long to update this. You know WDw, wipes you out from ages 2 to 92. I've been getting home and only doing a quick check and falling into bed.
DisneyisTerrific, I moved your second character group into the Disney parks group, to give that group 3.
Mazda, AWM signed up for a kiddo spot, and I can make Kicky something too, to make that a group of 3 if no other kids are interested.
Otherwise, this looks like it will be a very easy swap, with some small groups. More time to experiment with Flock!
