Hi RVCHAT,
You probably will find fewer dvc owners renting points right now on the rent/trade boards. I've been a member of this site and a dvc owner for 10 years, recently disboards changed the rules that a member needs 50 posts spread out evenly over 6 months in order to "advertise" their points for rent.
I tend to browse the disboards and only post when I feel I have something to add. Not another "Is the food at the HDDR any good" will I reply to. I have rented points twice via the boards and found it very useful and easy.
That being said, while the rent/trade boards don't seem very busy right now, check back for your next trip, you'll find many renters with past positive experience, references, a willingness to rent any number of points and accept personal/certified checks, and a going rate of $10 / per point!
Good luck - hope you can stay DVC, you'll love it.
(this is not a overt attempt to sell my points! Don't have any extra anyway)
