We road trip a lot and I will use a gym probably 1/week. I have never been refused cash payment for a "guest membership" for a day or a month. Crossfit Boxes will welcome you w/ open arms. If you have room in your house investigate the efficiency of a home gym. We have a treadmill, elliptical and a bike as well as free weights, kettlebells and rings. Privacy issues are important and I would guess that the manager in charge of the bottom line will accept cash, check or money order.
Hint, get a Nordic Track treadmill and a few kettlebells and become a monster.
