I'm reviving this thread because I'm staying on a friend's VGC contract this weekend and just thought I'd clarify the parking question. This is a direct quote from a DVC CM on chat:
Me: So I'm an owner at VGC, but this weekend, I'm staying under my friend's contract using his points (he couldn't make it, a bit last minute). I went to check-in today online and it mentioned a $35 self-park fee per vehicle. Is this correct?
CM: Great question. As long as you are staying on a reservation that was booked using Disney Vacation Club Vacation Points you do not have to pay parking. I think it is just a generic message no matter who is checking in.
So confirmed what I generally knew to be true, but thought I'd add to the compendium of information out there.
