Bob and Dot,
There are 60 timeshare units for 52 weeks. In July of 2013 there were 2,056 weeks sold with 1064 weeks still available.
I copied those stats from the info listed online when the first auction took place. Back in summer, 2013 yes: 2,056 weeks had been sold but a number of owners own two or three weeks so 2,000 owners maybe, plus or minus. We don't know how many units were purchased in the last year so this gives us a rough estimate on the number of owners, not necessarily the number of weeks owned.
