I have six of them and am planning a tourist camp. Each is being weathered and getting window glazing added, doors are all painted different colors and I have some spare roof sections which will become covered patios. Parking and roadways will be added as I go along. Some assorted lighting will help a lot, too.
I also found a smaller scale cabin made of softer material that will become an office and mail room and am looking for a larger structure for a store and general event room.
I may make a half dozen teepees like the old wigwam motels and maybe a trailer / motor home area as well. I might even add a riding stable for horseback trips through the woods and mountains.
The Plasticvile stuff isn't highly detailed but it make great basic structures for bashing. You might look into the Plasticville Collectors Association for more info an a whole raft of stuff you can make use of.
