Can't speak from personal experience. However, according to the 2008 Trailer Life Directory, the place has 223 total spaces with 52 available, indicating a large number of permanents though probably only seasonally occupied. Likely more of a residential atmosphere vs. an RV resort style. All depends on what you like.
Hopefully, someone who has visited there will chime in.
I'm sure you've already visited their website:
