From experience in the Seattle area, if you are in the USA you can get yourself passes for state and/or federal parks. In Washington state for example with a Discover Pass ($30 annual fee) you can park overnight for I believe up to two weeks. Not sure about the federal parks. Much cheaper than motels and no harassment from law enforcement. You're just camping! Move around as needed. Edit: pass fee.
