We loved Coronado and would stay there again in a minute. We stayed twice, first time we were given a free upgrade to a waterview room in Casitas 5 and were blown away. Second time, not so lucky, overlooked the parking lot ($79 AP rate, what should I expect?) - but the resort was still fabulous.
The Dig Site pool area is spectacular and has a huge spa. The waterslide compares to a waterpark version. I just love it. If you want quiet, there are several smaller pools scattered around the resort.
We didn't mind the sprawling layout of the resort because we enjoyed the scenery so much. If you want to be close to the lobby area, stay in Casitas 1 or 2, or the Cabanas (? #). I liked the atmosphere of Casitas the best - felt like a Mediterranean resort. Cabanas has a beachy them, Ranchos is a desert theme.
The bus service was efficient (better than AKL it seemed to me). We felt sorry for the masses of people waiting for the All-Stars bus at MK. Our bus stop was deserted!
The food court had many choices. We didn't eat at the main restaurant, but it looked good!
The atmosphere felt less chaotic and more laid back than some of the other resorts. The patrons seemed a bit older and quieter. But we were there during off-season both times. It is a conference hotel so there may be more business people (we saw some "suits" poolside...) - but it is definitely child friendly!
If you are trying to save money, want a great pool for kids, a laid-back atmosphere, and a luxury feel, I would definitely pick CSR.
A couple folks on the boards have great websites dedicated to CSR. I think EpcotFan is one?
