I remember Mutton Hollow! It kinda felt like what SDC must have felt like when it was just the main street area, before the rides. We went horseback riding once there; it was so much fun!
Honestly, I think one of the many factors that led to CC getting shut down was its hours. They kept advertising it as a "night park," but it was only ever open until 10pm! With SDC open from morning to 6-7pm, it just seems like people probably thought it wouldn't be worth it to go to CC after being at SDC because there wouldn't be much time available to spend at CC.
That's where Disney has a good layout in Anaheim -- California Adventure is DIRECTLY across from Disneyland, so people can go back and forth between the parks. Same with Universal Studios & Islands of Adventure in Orlando. Heck, even, to some degree, Magic Kingdom and Epcot; they aren't next to each other, but it's a quick ride on the monorail to get back and forth. And you can pretty much walk from Epcot to Hollywood Studios (wellll... it's a bit of a walk; but you can easily grab a park bus from one of the resorts right next to Epcot, and it'd take little time to get to DHS).
CC was just located way too far from SDC. And honestly, I feel like White Water is a bit too far from SDC, too. They need everything in a closer vicinity to each other... I know, though, that the terrain makes that hard. Maybe move White Water to the CC land and build some kind of transportation connection between it and SDC.
They also need some kind of shuttle-only dedicated road from the Wilderness Campground to SDC; right now, the shuttle has to go all the way up 265 to 76 and over to Indian Point Road in order to get to the park. They need a road that goes straight west; I'd certainly be more interested in staying at the Wilderness if the shuttle didn't have such a long way to go to get to the park. As it is right now, I prefer Deer Run because you can walk to the nearest SDC parking lot and catch the tram.
And... now I'm done. I've gone a bit too far off topic. OOPS.
