Although it annoys the crap out of me, WDW is significantly better than DL. It bothers me, because DL was built several years after the WDW one, and all of the "bells and whistles" should have been added, IMHO.
The moving through the hotel section is cool. Must importantly, though, the drop sequences are completely randon---you never get the same ride twice.
Can't wait until tomorrow night to ride the DL version again---it's my favorite attraction on both coasts!
