I have four children, 3 boys and 1 girl, all under 10 and since Feb '04 we've done :
Crystal Palace dinner... kids loved food, but not too much interaction
GF 1900 Park dinner... nice characters, very patient, kids thought food was ok
Chef Mickey's dinner... horrible interaction..we were stuck in dark corner and the characters came by for like 1 min, and we have 4 kids... It was Ds 4th birthday and Mickey didn't even stay long enough for him to slid out of the bench for a picture and hug

....food was ok
Ohana's breakfast.... GREAT interaction.. fun activities...too much good food
Garden Grill dinner...kids LOVED IT!!! Great food, abundant characters!! The characters came by so often that the kids seemed to *tire* of them :') (this was before they changed the menu, so can't talk about all of the food now)
Princess Breakfast.. limited breakfast food for my non meat eating son.. all he wanted was some fruit but our waiter never came back with it... Princess were GREAT!!! They all added some sweet personal touch to our visit. Very patient and kind.
This upcoming trip I am going to *try* to get PS/ADR's for:
1.
CRT breakfast for dd and I... heck, why not try for it at least right! Won't tell her about it unless we get it.
2.
Princess breakfast for dd and I.. dd loved the princesses and it is a great memory
3.
Liberty Tree Tavern.. have heard great things about this, and it is our kind of food
4.
Ohana breakfast.. Great fun from previous trip
5.
CRT dinner.. I can't wait.. dinner in the castle
6.
Chef Mickey's breakfast .. maybe we just had a bad night here.. let's give it another try.
My best suggestion is to go with your daughters tastes of characters. My dd just turned 8 and is real into the princesses. She wants to bring her princess barbie dolls so she can get a picture with them and the real princess!
