There's definitely some confusion then with the HGVC counselors.
I exchanged into HGVC Seaworld (I own HGVC) and was told I could only do this once every four years (and I called HGVC not RCI when I booked).
I also just booked an exchange (via HGVC) into Fairfield in Hawaii and was told that it was also a 1-in-4 (that I could not book that same resort for 4 years).
