Wow!!! You got a great rate!!!! Yes they are valid and they are NOT a scam. I got a similar deal last year $550 for a 2 bedroom in Bonnet Creek. Many times, the timeshare owner has points/weeks they paid for and never used. They rent for little money to keep from losing out completely. Redweek is a legitimate business. I use Redweek and TUG2.net for all of my vacation rentals. As I said, the cheap price is due to the owner trying to recover a little something back. There is a cut off time period for them to use the points/weeks. If they don't use them, they lose them. So they are renting to you for $500 so they get something back but it is far less than what they paid. RELAX. You will be fine. And "Redweek Verified" means that Redweek has verified their information for that listing. Once you go and have a GREAT time, you will be glad to pay the annual $18 fee to redweek because you will look forward to renting from an owner again!!!!
