How much does it cost to stay for 2 nights in a 33 foot camper?

Power sites are $35-$40 per night. Sites with no hook-ups range from $25 to $35 per night.

$10 a night

I'm not sure what rates are, but they can be found on the Washington state parks website. My stay was paid by my son and family. They also vary if you want full hook up or non hook up sites. They do have a place to empty tanks as you leave. Many of the sites will accommodate a 33 footer.
