Don, I'm sure unhitching a trailer would be fine on Wednesday.
There are two entrances off of Hwy-11, you want to go in the South gate, not the Main North gate. As soon as you pull into the bluestone driveway you will have a tree lined board fence on your right and a open grass field on your left. If you back the trailer into the grass field anywhere along the first 100' you'll be out of the RV parking area which starts at the first utility pole and goes West from there.
