I found eating character buffets was a good thing last year when we went. I have a 8yr DD and my friends DD was 11. They both enjoyed them, and we found we were plenty good to not eat again til dinner time when we mainly used our CS at one of the parks or at Pop Food court.
Here is a list of ones we took in;
-Supercalifragalistic Breakfast buffet (1900 Park Fare)
-Chef Mickey's (breakfast)
-Crystal Palace (breakfast)
-Crystal Palace (early lunch so we didn't really eat breaky other than granola bars etc and then had a good lunch at 11:45)
I hope to take in a few different ones this year to get a taste of how the other buffets compare and for future reference!
Enjoy..
