The One Day passes that you buy in the clubs are true one-day passes. The Groupons are single-visit coupons, though some people have been successful in using them like one-day passes.
And +1 to what everyone said above. Someone who travels 5 times a year might find no use for a 30 day or annual pass, but something like this is perfect.
