What to bring to an academic conference?

I’m a PhD student in the humanities getting ready to present at my first in person conference. 

I’ve attended and presented in virtual conferences before, but I don’t know what to bring to this one when I’m not attending from the comfort of my own home. Do I need business cards? Should I bring snacks/a water bottle?

Keep it light.  Try not to be the person with the huge bag that explodes the second you sit down.  Laptop or iPad, one notebook, pen, maybe a water bottle or coffee cup.  Hand sanitizer, etc. charger/battery pack.

Comfortable shoes.  Questions to ask.
