My girls did this last summer. You can start checking in at 1pm around by GF Cafe. The kids eat dessert first, then lunch, play hide & seek with Alice & the Mad Hatter. The each received a small bouquet of flowers to take with them & had their pictures taken with Alice & Mad Hatter. The pictures are put in a decorative folder & are autographed by the characters. My girls had a good time. There were several older & younger girls there too. My DH & I used this as the time for a nice lunch right next door at GF cafe.
I'm trying to pull some of the pics off my computer, but not having any luck.
I thought it was worth the money & would let my girls do it again if they wanted to. You book thru Disney dining.
