I'm not sure how they purchased it. I made the purchase less than 2 weeks ago so it's more of a last minute trip. I received an email from RCI within 45 minutes of paying for the trip with my guest certificate.
I have thought about purchasing a resale timeshare since we rent so many of them either through owners or SkyAuction. I don't like the new SkyAuction vacation certificate website and it seems there isn't as much availability these days. DH gets 5 weeks vacation per year and we try to take at least 3, week long vacations per year. I would love to have access to rent DVC.
