Its been about 4 years since i have visited, but in all of my trips to WDW, many times I have gone to the Poly, Grand Flor., and once the Yacht club for breakfast, had my car valet'd, and after breakfast gone to the park for the day on the monorail (at the yacht club, it was a boat to Epcot). When I first began doing this, I usually didnt even have a PS (now called ADR?). And of all of the times ive parked at a deluxe resort, I was never questioned about it. Only if I would be leaving after breakfast or staying for the day. Things were more strict at the gate to the MK, when I had early PS's for breakfast. (before official park opening)
