evening hours at all the parks. I found MGM still kind of crowded. For us on 2/2, MK was empty. It was also lightly raining. We did Pirates, splash, Big thunder, Haunted Mansion, Snow White, Peter Pan, Pooh, Teacups, Indy 500, Space, Buzz (many time!), TTA, etc all with no lines. It was fabulous!
I found Epcot and especially AK a let down, with not enough open. with only Dinoland in AK, the lines were kind of long!
All in all, I think having each park with an early morning and a late evening is a terrific idea.
