Cindy,
I'd heard for years that POTC was better at
Disneyland, and I was skeptical. Until I finally got to Disneyland a couple of years ago. It's a lot better. The ride starts off going through a bayou, and the ride's "story" seems to actually make better sense. One thing I particularly liked was that the smoke in the scene of the broadside attack by the pirate ship on the fort actually seems to FILL the room.
Maybe it's because the DL space is cramped, it feels more intimate, maybe more interesting. Dunno. There are subtle differences in the ride, though.
