Miles for use of hotel gyms?
 

Hello,

Which hotel program gives miles for using their fitness centre (as a non-resident)?

I am trying to pick a gym to use in Warsaw, and was looking at the hotel-based ones as they tend to be the nicest. At the same time, I'd appreciate a chance to increase my miles balance in any of the major hotel programmes if it were possible. To be sure, I would NOT be staying at the hotel at that time, only buying gym membership as an external visitor.

Any ideas? We have Sheraton, IC, Hilton, Marriott and Hyatt here. Sofitel is also present but their gym was pitiful the last time I stayed there last year.
