There are no DVC resorts at DL yet. They have announced DVC at Grand Californian but have not started selling it yet. Members can use their points to stay at the 3 DL hotels but it is significantly more points per night than staying at a DVC hotel. I think it's in the 20-50 point range per night depending on which hotel, type of room and time of year. The most expensive being 93 points per night Fri-Sat nights Grand Cali, concierge DCA view.
At $10 per point it may not be much of a bargain but then again I don't know what the rack rates would be though.
