hertamaniac,
I don't know if Disney owned them (leased? loaned?) but they were rented out by Disney (they stayed parked on certain sites/loops). In the early 70s there were a handful of Airstreams. But in the mid-late 70s those were replaced by many more Fleetwood travel trailers known as Terry Trailers. Sometime in the mid 80s the cabin loops were built and the Terry trailers were done away with and the first style of cabins called Wilderness Homes were placed. (which opened up more campsites since the Terry Trailers were no longer on them). Then the log cabins we know now replaced the Wilderness Homes starting in the late 90s (it was apparently a multi-year cycle to get all the WH changed out).
Now there are recommended companies for trailer rentals but non-recommended rental companies are used also by guests. The vendor-Disney side is not as cozy for the non-recommended but it certainly works.
I like the suggestion of a 2/2 cabin - maybe a double wide cabin that we could call, oh I don't know,
what's the hot term Disney likes to use for the exclusive stand-alone accommodations?
Oh yeah - Cabin Villas!

PS - or maybe we could call the 2/2's "Chalets".
