We stayed in a Jr. Suite at the Swan in Nov. 2000. It was an upgrade due to a minor reservation error and much appreciated. Don't know where any room floorprints are but I'll describe as best I can.
First, it was not really two rooms. There was no doorway other than the bathroom. Essentially, it was a good size "L" shaped room. One leg of the "L" was the dining area with a large (4 person) dinnette table. There were also a couple of dressers or maybe one dresser and the honor bar in that area. The other leg of the "L" was larger and had the bed (queen I think), TV and a sitting area with fold out couch, easy chair, and coffe table. Very comfortable. What we really liked, aside from the generous floor space, was the fact that it was a corner room with views in two directions. We had a view of the Dolphin from the sitting area and a view of Tower of Terror from the dinnette side.
The bath had the bath/shower, toilet, and one sink inside and an additional sink outside which was very nice.
There was an iron and board, hair dryer, and safe.
Don't know if all Jr. Suites are like this one but it was much nicer than a regular hotel room but short of a true suite.
Have a great trip!
