I looked at all the RV/Trailer Parks close to Seattle. They were either over priced money traps, or crammed in so tight that there was no room to turn yourself around.

 I came across North Sound RV Park and I found it charming, quiet, clean, drama free and with space for personalization. Reasonable pricing for your space and that also goes for the Laundry Facility.  I also can't say enough about management.  They're great!  So nice, helpful and knowledgeable.  They do have rules, (reasonable), that keep this place pleasant to stay at. I'll always recommend them.
