Ok...my 2 cents on the whole Adventureland theme thing....
The original theme of AL at the MK was "tropical."
You had the tropical entrance, the Treehouse, the Tiki Room, Jungle Cruise, and the food and merch locations. All with a general "tropical" theme. Lots of greenery, lots of colonial architecture, etc.
So far, so good.
Then Pirates comes along. Never intended to be in MK at all, much less in Adventureland. It was stuck there just because they didn't have a better place to put it. In order to maintain some sort of cohesive theme for the existing AL, they put PotC sort of around the bend, out of the main sightline of AL, and named it's location "Caribbean Plaza". Sort of a mini-land.
Still ok. It's a bit of a stretch, but it's still tropical and placed in a way that it doesn't interfere.
The Carpets, however.....that's another story.
They wanted a quick, cheap way to add capacity. Carpets did that. They also caused them to change the "tropical" and "jungle" themed areas in that part of the land to a vague desert/Arabian theme. So, where once you could stand in the middle of AL, turn in a circle and be surrounded by the tropics, you now had a giant Arabian thing plopped down in such a way that you lost all sense of a cohesive theme. Can't knock the ride on the grounds that it helped capacity, because it did that. Can knock it for further diluting the theme of the land.
Same can be said for, um, let's see.....
Speedway in Tomorrowland
Monsters, Inc. in Tomorrowland
Nemo in Future World
And how 'bout this one...20K in Fantasyland at MK. Would've been a better fit in Adventureland.
