RV park near Eastport, Maine - open after Columbus Day

I want to go to Eastport, Maine, on about October 19 for a few days. I can't find any RV parks in the area that are still open then.

I have a 40-foot motorhome.

All of the following will be closed:

Eastport: Seaview CG

Robbinston: Hilltop Family CG

Calais: Calais Motor Inn & Keene's Lake Family CG

Does anybody know of a place that would work for me?
