Ready for "Bisty World"!!!

We have officially began our countdown for our trip to DISNEY WORLD (or "Bisty World" as Emma calls it)!!!!  I have been making reservations for our character dinners and mapping our "attack" so that we can do the most in the shortest amount of time...considering Emma is 3 and her cousin, Thomas is 2 1/2!!  We leave for our probably 14 hour drive in 6 days and 5hrs!! We will be making this trip with 5 adults (me of which is prego!) and 2 toddlers...all in the same vehicle!!  This should be fun!!  I really can't wait to see Emma and Thomas's faces light up when they see everything! I just hope they're not scared to death to meet the characters... we have a MAJOR meltdown at Chuck-E-Cheese, if the mouse is there!
