We stay every now and then, but it is when we are traveling in the car and not with the camper, we " NEVER " stay in a hotel/motel yuk.... we take our sleeping bags and stay in the camping cabins in a KOA.
back in 2002 we took our kids on a 32 day outwest loop, 11,500 miles, taking the camper was out of the question for the time and miles we needed to cover.
we stayed in KOA cabins every night except for Yellowstone, Mount Rainier, Yosemite, and Grand Canyon, It worked well for us, they always had a pool, and my wife could wash laundry at night after the kids were in bed, while I checked over the car.
