We cheaped out and did the Wonderland Tea Party for her instead (about $40). It's basically fun with Alice and the Mad Hatter.
There's stories, a food fight, little sandwiches, etc.
Mom dropped DD4 off and went to the Garden View Grand Tea while that was going on.
Afterwards Mom picked her up and went back to finishing her own tea with our DD.
Turns out, DD4 thought her tea party was just okay but really enjoyed going to Mom's "tea party" even better.
They gave her a pitcher of "tea" (chocolate milk) and some sandwiches and she even got to pick a dessert.
When I asked about going back, she is very exciting about joining Mom for her tea party again but has no desire to redo the Wonderland Tea Party.
