I'm sure Henry is going to love breakfast at Hollywood and Vine. We have eaten there I think 3 times. The food is just kinda the same old breakfast food, but we always leave full. But the character interaction is great. They have dance time, where the kids get to go to the middle of the restaurant and dance with the characters. Here is a picture of my DS last time.
He was so excited that Oso was there, we hadn't told him that he would be there. I know that it doesn't look like they are dancing, but they are or singing or something at that particular time. It's a lot of fun.
I'm so excited about Playhouse Disney changing. I knew nothing about that until you mentioned it. My DS always has to go see Playhouse Disney, so it will be nice that it has changed. I'll be sad though, because it appears that Pooh won't be included, since he isn't on Disney Junior. Pooh is my fav, so I'll miss him, and my DS loves Tigger. Oh well.
As far as Epcot. We did go during the Flower and Garden Festival 2 years ago, and really enjoyed it. They had a lot of activities for kids and I loved the flowers, they do a great job. You are gonna enjoy it I'm sure.
As far as ESPN the weekend, I think we are going to avoid it if at all possible. Nothing that I have read that is a must do for us. Have you found anything really exciting going on during that time?
