We have rented points for a trip to BWV 9/26-10/3 and are wondering... I understand that Ultimate Park Hoppers can be purchased in advance at a small discount by anyone staying at a Disney Resort. I also understand, from what I've read here on the board that DVC members and their renting guests can get a discount on UPH's. My question is this, if the latter is true, must these be purchased inadvance to get the member discount, or should we go ahead and call the BW and purchase them at the regular discount?? Also, how can I find out how much the discount is??
