As long as you do not have an outstanding mortgage, you can give it to another. You have to go though the process of closing and transferring by deed and give notice to
DVC.
DVC does not have a right of first refusal as to a gift but you still need to go through the same process and it will sign off on it as long as there is no outstanding debt -- note if you are on monthly dues payments by withdrawal from your account, the recipient (or you) will likely have to pay off the dues for the year at time of closing because the dues for the entire year are considered an outstanding debt that must be paid at time of closing.
