My parents are DVC members and stayed at the VWL last December. Since I am relatively close to Orlando (closer than most, but actually it's still about 2.5 hours away), I came up to spend a few days with them in their villa. Upon their arrival, they told the front desk that they would need 2 parking passes as I would be joining them later in the week (they had rented a car themselves). No problem and they happily issued a second pass which I placed in my car when I arrived.
Since they were in a villa, occupancy levels being exceeded was not an issue and I honestly don't know if they had me on their reservation at all, but I suspect so. My dad is always very by the book and I know that he made the desk staff fully aware that I was staying in their room (albeit on the pullout sofa, but it was still lovely to see them) for part of their stay.
Hope this is helpful!
