Hi!
I really have no advice, but I just rented points for the Poly at the 7-month mark today for our stay in August. I used the rental board on this forum. Within the 7-month window, points can be used at any DVC resort, so you don’t necessarily need to rent from someone with Poly points. If you can’t find a renter on this forum, there are quite a few FB groups for renting points.
I find renting from the person directly, rather than through David’s or other rental agencies, a couple dollars cheaper per point. It’s super easy. I only contacted the renter last night, and after a few emails back and forth, I paid and received the confirmation number, and I have the reservation all set up in
MDE already.
