I have to see Stitch Encounter, simply because Alien Encounter was one of my all time favorite Disney attractions (yep, I'm a sick little space monkey) - I even made sure that every time I entered, to sit near some stupid parent and their kids who ignored all the warnings that the attraction may be scary...
Maybe I'll just start screaming (ask anybody who's sat near me on a coaster when I'm in fine screaming form) the second the show starts?
