Thank you for all your suggestions! they were great. Here's my plan as of now. I'm going with 2 girls (10 and 4) and hubbie. He's the only one who wants to do space mountain so...He goes to space mountain at rope drop while the girls and I make a beeline for Dumbo, Carrousel and Peter Pan. After riding Space Mountain, hubbie gets all of us FP for Buzz Lightyear and meets us at the teacups. (if there's a short line, we'll do the speedway, otherwise, we'll skip it) Then we all go to winnie the pooh and snow white. Then, depending on time, we either go on Buzz or do Breakfast and then do Buzz and IASW.
Then we can do adventureland, fronteirland and haunted mansion in the evening or a different morning day (depending on May hours when they come out).
