Trying to give you suggestions about places to stay on your way thru Washington. Lots of people balk at staying at KOAs, but the ones I mention here we had good experiences with!
We made a trip to WA from WI a couple of years ago. We spent one nite at a nice KOA north of Spokane and visited a cool Ukrainian deli in Soap Lake for lunch. Stop at Lake Lenore Caves after visiting Grand Coulee, short fun scenic hike, no need to unhook. We did another KOA in Ellensburg and visited Roslyn where Northern Exposure was filmed. We also went down to Astoria, Oregon via Mt Rainier and Mt St Helens, both worth it.
