I cry and then run off....
but seriously, if theres a group of you, and you said canceled memberships, possibly buy a decent bench between you guys with dumbells as well etc. (thats if you know them well enough etc) Can sometimes be better then standing around not doing much if you always have to wait. Can do almost all (if not all) muscles groups with free weights. Cardio, nothing beats jogging outside... unless its pissing down.... Just a suggestion, defo don't have to take it at all.
But for over crowded stuff, just be confident and use machines that are free until one you want is available then go use it straight away, don't hover.
