I've stayed off-property in Anaheim, which I wouldn't consider for WDW. Disneyland really is within easy walking of so many of the Good Neighbor hotels that distance isn't an issue. For me DL and DCA are entirely the destination and all I do at the hotel is sleep, so not being on property isn't a big deal.
A few notes: Ramada Maingate is a little noisy, and Best Western Park Vue Inn isn't anything too fancy, but it's serviceable and clean and the location is fantastic. The Anaheim Marriott is really nice,but I don't remember if we didn't walk because we couldn't, or if we were just lazy.
