Not counting Marco Island (under construction) and the Grand Residences, there are 47. Many of the others that we don't have maps for are single buildings (e.g., Custom House, BeachPlace, Grand Chateau) for which a map wouldn't be useful. The Reviews for some of the others include photos of the resort, which appear sufficient, even though they aren't "maps". Several resorts (e.g., in Spain) are non-U.S. properties for which no one has volunteered that a map exists.
I'm always happy to add a map to the reviews if someone volunteers one that isn't on the list.
