Bleh, sorry, but we hated Alien Encounter. I agree that something needs to replace HISTA though. Actually i was reading in the
Disneyland encyclopedia that Alien Encounter was supposed to be put in Disneyland but they changed their mind. Hmmm.... I'll have to look it up again because know I can't remember why they changed their mind. I think it was supposed to go where the Pizza Port is now.
As for what ride I would want, i would have to say Rockin' Roller Coaster. Actually, what I would really want is Blizzard Beach but that's a whole park, not one ride so I guess that doesn't count.
