I travel everywhere with my hammock. Once I had to be in a city for a convention, but all the hotel rooms were full.
So I rented a U-haul truck for $19 and change, slung my hammock in the back of the truck and slept well.
Bathoom? I picked up a used laundry soap bottle and cut the spout out of it. In the morning, I watered the bushes.
Shower, change. Rather than use a gym, I paid a maid at a motel (tres dollares) and used the shower in a vacated room. Shaved. Fresh as a daisy, made the convention and sold my outdoor books to dealers.
Back of a U-Haul is #1 if you travel a lot.
