Our spin room is 100% open at the gym I go to. No doors on it, but it's kind of "back in the back" of the gym. It's pretty secluded. Has a climbing wall all around the room too, so you can spider-man around the room while spin classes are going on. Pretty fun stuff.

My gym owner doesn't mind if we use the spinning bikes, he just drops by and checks on us every now and then.

There's a about 12-15 members he'll let do *anything*, and the rest just kind of go about their business. Luckily, I've built a very strong, well-to-do relationship with the owner, and he'll let me try / use anything I want to (within reason of course). Everytime I walk through the gym doors, he even changes it to the rock station for me.
