I stayed at the KOA during my PCT thru hike, entirely with the intention of having a nice relaxing place to stay.

the KOA itself is nice. There's a pool, a clean bathroom and shower and a nice laundry room. The tent set up is affordable, $35 if you have a vehicle and $15 if you're a hiker. There's a big grass field where you can set up your tent right next to water and all of the amenities, and the KOA has free wifi which is always a plus.

The catch is, the KOA is stationed between a busy road and a railroad... so all. Isn't you end up hearing the train blasting it's horn and come morning, you're woken up by the constant influx of cars.

If you're an RVer, than you can probably avoid the noise. However, as a tent camper, it wasn't the most relaxing place to stay.
