Now how did I know, when I saw the thread title, that you would be the author, and it would be a rant about said gym? ;-) (I remember the same complaint last year...that's how!).
Maybe it would be a good idea to use January as 'at-home-workouts' time? If you plan it, you can set up a rotation that will keep you in shape until all the new-year's-resolution drop-outs stop going (about the third week in January, wouldn't you say? LOL!)
I can only imagine what a pain it is this time of year (and I only WANT to imagine, and not experience it!)
