I'm so glad I found this list of good, cheap hotels near Disneyland. All these hotels are within walking distance of Disneyland and all of them are a lot less money and some are closer to the main gate than the Disneyland hotels.
Best. Hotel pool. Ever. The Biltmore in Coral Gables. One of the most beautiful hotels I've ever visited. If you're in the area on business during the off season, the rates are surprisingly reasonable.
