i have to side with the PPs:
if you are only going for a few days, the passes are very expensive.
stretch that vacation to a week, & the ticket prices are actually a very good value.
we've paid less for US, but found ourselves bored by the 2nd day (we had 5 day passes). we were not impressed with the cleanliness or too-young drunken hordes either.
imho, great adventure is overpriced
and dirty, with little to do.
a few days in montauk cost about the same as WDW, with more expensive food & less to do.
there are many beautiful & exciting destinations outside of WDW, but every single one is waaaaaay more pricey. also, we don't come home relaxed & refreshed like we do from WDW.
we've gone to WDW 2-3x a year, & are still discovering new things to do & see each time. another big (HUGE) factor for us is safety: nowhere else would i have allowed my pre/early-teens to wander a resort, or enter a park by themselves (with a "buddy" & a cel phone ~ "just in case"
). lots of times, i will wander around the resort or a park by myself at night ~ never have i felt threatened or even uncomfortable.
all in all, we've found we get the most "bang for the buck" at WDW ~ good thing we enjoy it as much as we do
