As far as the fear of too many locals coming in on the weekends... There is very limited public access around the resort.... there
is a public beach adjoining the property to the north.... but there is very little parking, so you just won't find
that many locals there.
Besides.... the east coast - in that area, at least - does
such a wonderful job with its parks... there are parks every couple of miles, it seems - some with very nice facilities.... so the locals really seem to spread out.
...It's nothing like we experience at the more popular beaches over here on the west coast.

Those crowds can just be overwhelming...
