So, what can you bring with you? A small purse or a tiny backpack is A-OK, as long as it's smaller than 12" x 12". But, don't even think about bringing a large bag or a briefcase – those are a definite no-go!
If you're wondering about specific items, like cameras or water bottles, the Exit In has got you covered. They allow point-and-shoot cameras and refillable water bottles, but leave the pro cameras and outside food at home, please!

The Exit In also offers a bag check service, so if you do happen to bring a bag that's too big, you can stash it safely while you're inside. It's a pretty convenient option, if you ask me!
