We have boys ages 7 & 6 and we do the opposite. We go to Adventureland. Get a FP for Jungle Cruise, hit Alladin, Pirates of the Carriabean, Splash, BTMR, back to Jungle Cruise then we cut across thru Alladin to the shops in Frotierland past Liberty Sq and up to Fantasyland (past Haunted Mansion). It's a bit of walking, but we usually manage to be in Fantasyland by 10:30 at the latest. We get a FP for PP, do SW, Carosuel, Dumbo, SnowWhite, etc. As we head towards Teacups grab another FP for Pooh. Sometimes we head to Toontown or we head towards Buzz.
My dad was amazed last year at how many rides we got done before lunch (11:30) since we are up so early.
This year with my dtr. turning 3 we may need to do one morning the opposite and hit Fanstyland first, but really she's never missed anything the other way so I don't know if I want to mess anything up.
Good luck!
