We live in Washington, just 20 mins south. While I've been in the area many times, last time I was there (late 2020 I think?) I wondered what was being built. They built a restaurant, RV sites, cabins, etc as you have seen on the web. No, I have not been there since they built it up, HOWEVER, if you go to google maps, type it in, you'll see pics that come up on that left side bar. Also, the 48 google reviews it has are very positive....food, site, trails, etc.
I have it on my list to stay at...even though it's 20 mins or so from home. Looks high end, river life type of style. I'd give it a try....we are going to, hopefully in '22.
