We just stayed there over Labor day weekend for the 1/2 marathon. WE LOVE IT! My expectations were low, but we didn't care because it was a short trip that wasn't going to be spent at the hotel at all.
We ended up being pleasantly surprised! Nice rooms, very comfortbable beds, quiet, indoor hallways, plenty of parking, nice pool area, and a short walk (for us) to the mickey and friends tram.
An example of a short walk for us is from Hojo to the front gates, a long walk (but still doable) for us is from Sheraton Park hotel on Harbor.
They were completely booked that weekend and yet we didn't see one person in the hallway, nor did we see anyone even walking to the tram. Like I said, very quiet and not crowded at all. Very secluded.
The tram may take up some time but at least you're not stuck at crosswalks with mobs of people. Just something to think about.
