This is so much fun to read as I will be feeling the aforementioned goosebumps soon (look at my countdown clock for July 5th....ooohhhmmyygosh!!

)
Anywho, I've got some no one else has mentioned:
-Once on property, ducking to look out car window to see top of ToT or SE or even Space Mtn. sometimes and subsequently freaking out even more (in a good way!) that we're there!
-Checking in at OKW (our home resort as DVC members and where we typically stay) and the smell of the wood floor in the lobby there and hearing the island music -- OR, entering the lobby of wherever else we're staying (like WL or BW) and letting your eyes adjust to the light in the lobby and....WOW - GOOSEBUMPS!!
-Watching Resort TV for the "Zip-A-Dee-Do-Da Tip for Today medley, like someone else said, but also to watch the commercials for each park even though I've seen them all umpteen times
-Waking up in one of the resorts and suddenly realizing where you are and what you're going to do today!!
-Stepping outside of our room (or right outside at OKW), all packed and rarin' to go w/all the family - so much excitement!
-Getting out of car in one of the Parks' parking lots and practically skipping, a la "Follow the Yellow Brick Road," to the tram or front gate (the walk BACK to the car, however, always seems to take FOREVER...)
-Hearing the 20's, 30's music in the gardens outside ToT while waiting in line (and all the mist and creepiness, too)
-Posing for the obligatory photos for parents or family right outside "The Big Ball" at Epcot, standing on the ledges around the flowers
-Going into Sci-Fi the first time for each trip, and hearing all the waiters/waitresses yell "Lookout! Aaahh!!" at the clip of the growing man (similar the 50ft tall Woman) throwing the giant needle into the doctors ("We're only trying to help you!") What's the title of that movie? I can't think of it now.

That's kind of a weird one anyway
-Finally, riding that FIRST RIDE of the FIRST DAY of the trip - usually a thrill ride like Rock-n-Roller Coaster or Dinosaur or ToT or Splash Mountain, and me jumping up and down through the whole line cause I'm so happy!
Those are my contributions...anyone else?
