au contraire MW there is a character breakfast at IOA with the Cat in the Hat and the Things (1&2) but nothing in the evenings or mid day.

We went two years ago so my information is dated but the breakfast actually pretty good. It was standard american breakfast buffet but it was fresh and the servers and the characters interacted with everyone well.
We had the Cat in the Hat, the Things and the Grinch.
