Now this seems like something that benefits everyone--the hotel's power bill is somewhat reduced, there's a good chance it might make some extra money in the restaurant (if the meal ends up costing more than the voucher), and the guests get exercise.

If all facilties that had cardio equipment used them to generate power, that would be beneficial both economically (saves on the power bill) and environmentally (less fuel burned).
