Anyone been to cons? I’m going to my first tomorrow and I’ll be going alone.

Any advice? Other than wear comfortable shoes? I’m planning on bringing some cash but do booths take cards too? I’ve looked up parking and am trying to plan getting there. The convention center website said you can’t bring in food. Do these things usually have food? I am a Cranky Ass when I’m hungry. I’m planning on bringing advil. Oh and I’m assuming I can bring my backpack. People will be cosplaying so a backpack shouldn’t be a big deal right? The security and safety section of the website didn’t say I couldn’t.

Any etiquette things I should know? Or safety things?
