So far the hotels I've been staying in have had gyms. At very least I need an exercycle machine or something like that. But the hotel I'll be staying in for the next few days doesn't have that. Is it possible to use those centers like 'crunch' and 'bally's' on a one time pay per use basis? Any suggestions would be appreciated. I'm not keen on street jogging in a big city that I don't know, btw.
