We did go to Epcot for a few hours. Son and DH did Test Track and we all spent a long time in the Finding Nemo building. We did Turtle Talk with Crush and he picked Son to talk to! It was cool and really funny.
Epcot was a neat place, but it just wasn't for the kids so much, which is why we only spent an afternoon there.
On another note, have you ever done Summit Plummet? Never again. You have to psych yourself up to scoot your body over the edge and drop 120 feet, scraping your shoulder blades the whole way down because you're so tense from picturing yourself falling over the edge. Oh and also your swimsuit bottom isn't the only thing that goes straight up your butt.
