It is also important to research and understand the differences between a DVC rental and getting a reservation from Disney.
First of all, availability is different and if you are going at a busy time (and the first week of December is busy for DVC), you want to book close to 11 months out.
Second, the reservation will stay in the control of the member. They own it and will be the only one who can make changes, add the
DDP for you (if you want that) or add ME.
Third, there is no daily mousekeeping with DVC. Depending on the length of the stay, depends on what you get.
The biggest piece, I think, is the cancellation policy. Since this is a friend, it may be different, but it is typically more restrictive.
But, you can get a great deal on the DVC villas this way, especially if the pin you have does not include the DVC rooms.
Good luck!!!
