We are booked to go on a 7 night cruise in may and are then going to do 10 nights at WDW. However we have some family that want to come with us and stay in the same resort. They would be flying out with us but staying in WDW the whole time (18 nights). I was thinking of renting some extra points from someone on the DIS but wasnt sure how it would work? Do they transfer the points into my DVC account?
