June 1993.
My brother had first told me he heard about it the year before, but we didn't bother to check it out on our 1992 trip. So the next year, I remembered that my brother had told us a little about it, and we went over to the sales office (Commodore house if my memory is correct) and looked at the models.
We purchased then and there, and stayed that night.
Wow, free passes, total versatility compared to any other timeshare I knew anything about, and on Disney property itself with bus service everywhere. What else could you ask for?
Memories: How about the old room door locks that had the plastic card keys with holes punched in them instead of similar cards with magnetic strips as used today.
And the little shelf inside the entrance door with the key symbol printed on it, where you were asked to leave your keys when you vacated the room at checkout.
