My husband I stayed at the Polson KOA (Polson, Mt) one night while we were there visiting a friend and his family. It's convenient if you don't want to spend too much money on a hotel room. The place looked really pretty and the Motorcoach resort attached to it was also pretty and looked very well maintained. You could even sleep in the back of your car (if you have room). We slept in the back of our 2015 Subaru Outback. They have well maintained showers and bathrooms that look like they get cleaned every day. You should wear bathroom slippers or flip flops or something to avoid potential plantar warts in case someone who had it showered there. There's a small gift shop, where you go to check in when you get there. It's kind of like getting a hotel room, except you sleep in your car/tent/camper and walk to the main building for bathrooms/showers. For food, you can drive to town in Polson.
