When you rent points from a
DVC member, you are essentially making a contract with that person and taking Disney out of the equation. When you look through the rental board and find someone who is offering the number of points you need for the resort you would like, you contact them via the board, e-mail or a private message. They will then check availability at your preferred resort and make the reservation for you if the terms are aggreeable. Most people charge around $10/point. Things you want to be aware of:
1) Both the renter and rentee have to place a certain amount of trust in one another. You should get a signed contract stating the terms of your rental. You will not be able to contact member services to change your reservation or even verify your reservation (although you can now verify on the website). The renter controls the reservation.
2) I recommend using paypal. I would NOT send a check, money order, etc...
3) You can still use Magical Express and purchase the
Disney Dining Plan but the DVC member must set them up for you.
4) Renting points is a great way to experience DVC and secure a larger room for your family without having to pay Disney prices, but can also be a little nerve wracking. When choosing a renter, most feel it is best to go with someone who has been a DIS member for a while and has a large post count. Scams do not happen very often, but are always possible.
As far as which resort, how old are the grandchildren? What parks do you envision spending the most time in? I think BLT would be a good choice because it is on the monorail and doesn't have huge, long hallways to cut down on walking for your husband. Good luck with your planning...we have rented points twice and have been very pleased!
