I own week 51 at the Royal Sands and week 52 at the Royal Mayan both in Cancun and was looking for places to list week 52 for rent. I have used a couple of the usuals like
www.tug2.net and
www.mexicondo.com. I considered redweek. I listed with Craigslist.
Then I began thinking of auction sites. Are there any other than eBay where a private seller can list a timeshare week? eBay is a bit complex but I will be approved by next year.
This year I found a renter through TUG. But if good auction sites are available, I might try one for next year.
