Last year my family splurged big time and went to Disney for the first time ever (31 yrs old first real vacation in my life). We had a wonderful time but spent a sizable amount on a 6 night all inclusive Disney extravaganza! So this year my dear husband realized that there is a point to vacations and we should take another one. However we are severly limited on the budget (dang the economy). Even the wonderful 7/4 deal would be outside my meger vacation budget. So after several days of number crunching I found we could do US/IOA and a 5 day off site hotel or go to Gatlinburg TN for 5 days. So i am trying to decide so i can get reservations made. I have one child at 44.5 inches who loves fast rides roller coaster etc. He was very disappointed about not being able to ride Rockin Roller Coaster. I have went through the list of height requirments and wondered if the 4 rides he is too short for will greatly diminish his ability to enjoy the park? Are there still plenty of other "thrill" rides for him to enjoy? Is there as much to "see" as in Disney (characters themed buildings shows)? I remember just being in awe of the sights and wonders off WDW. Will we be disappointed visiting US/IOA after the grandor of WDW?
