Where to take a quick nap?

I commute to class a couple times a week and live very far from here (2+ hours). I have 3 hours between classes and I get up super early, so I’m always tired. I don’t have friends or access to a dorm. I can sleep in my car, but I don’t feel safe doing so.

Where do you guys take naps? Do you have any idea where I can recharge for a bit?
