I always unplug. Only takes a moment. Every time I go back to the truck to resume towing - rest stop, overnight, etc - I do a walk around checking things, including the plug.
We did an "overnight" at a hotel on our way to Disney World years ago. I thought the kids would want to use the pool, we could use the hotel shower, and we could have breakfast at the restaurant. Nope - kids didn't care about the pool, our camper has a shower, and we left too early to have breakfast at the hotel.
Later trips we just found campgrounds with drive thru campsites. Cost less than a hotel room too!
