I can't say for sure, but when we visited last Summer with our small Scotty in tow, we were greeted in the office and given the details as well as a price sheet. In the office it was just me. My wife and daughter were in the car.
I was clear that our Airstream was a few years away from usability and that we were not entirely interested in a seasonal site. We just hoped to come down for extended stays at the shore.
We were encouraged to drive around the place and see what we thought. We drove back through the "permanent" sites and checked out the Airstreams stored there.
I did not get a cold, unfriendly feeling.
