We took over my parents timeshare in Kauai when Mom was unable to travel anymore. It was a lovely, old place right on the ocean. We stayed there twice, the yearly maintenance costs doubled each year.(did I say it was an old place, easily 1960's) We decided to give it back, had to wait until someone wanted to buy it (which happened within a couple of months).
All of the shares "expired" on a certain date anyway, and they remodeled the entire place. We got an offer to rebuy, not as a time share, but as full owner of a condo. Couldn't afford the million dollar price tag! And we had concluded we liked the option of going other places,
Nice memories, though.
