Totally depends on if you are an early riser or like to sleep late, or if you are planning on getting to the parks early or you just want to take your time and relax. Plan breakfast accordingly. If your set on a character breakfast Chef Mickeys is decent, food is just so-so, but character interaction is good. Don't know if I would pick it for an adults only breakfast, you are going to be sitting among lots of kids!! But it is a fun place.
Are you going for breakfast or dinner? We had a late dinner there last September, 9:30 I think. Anyway, I was afraid the buffet would be picked over, but it was full of fresh food. And we got the most attention from the characters because there were so few diners there at the time. Towards the end the characters really cut loose and put on a show!
oops, should have mentioned it's for breakfast. I'm normally not an early riser at all, but I do make exceptions on vacation.
As for going to the parks afterwards, if we'd go early yes, we would go. If we'd go late, I'd like to go the Holywood Studios first but am wondering if it will give us enough time there (HS open at 9.00 that morning, we'll be going by car)
