Just because it's winterized, doesn't mean you can't use it. Just don't use the plumbing. Go somewhere that has bath houses that you can use as if you were tent camping. The only difference is that you will have a kitchen (minus sink usage), comfortable bed, living room, heat, tv, etc.... We did this, this past January. Went to Myrtle Beach for a long weekend. Had a spot ocean front. We carried water with us and made sure to pour it down the sewer hole outside. Heated water up on the stove and washed dishes (pots/pans) in a wash basin. It was great. The only thing we would do different was be a little closer to the bath house. Having a portable potty might be good to have for the night time bathroom trips. Can just dump into the sewer when needed.
