We have parked at BWV, Poly, and POR w/o having reservations and being checked off a list. We frequently go to the Poly beach to get a drink from the pool bar and watch Wishes, and will park at BWV when going to ESPN or maybe even to Beaches and Cream for some ice cream on a nice evening when we feel like walking. And, we visit POR to see Bob Jackson at the River Roost Lounge on every trip....all of the above w/o reservations. However, we also do stay onsite every trip and therefore, do have our DVC placard on the dash AND we also are AP holders. Even with the above I would not chance parking in a resort where I was not a guest for more than three or four hours......I would never consider parking there for an entire park day. I say this because sometimes when we ARE staying at a certain resort it's extremely frustrating to drive around the lot looking for a spot ......knowing that a percentage of the vehicles parked there are NOT staying there and yes, I have also seen cars being towed from resort parking lots. I have heard they are cracking down more on this, especially at the problem areas like BW and BC. I read somewhere that unless you are staying at the BWI or BWV they are not allowing you to park in the close lots, but, rather directing you to the satellite lot across the street (behind the Hess station).
