Q. Do you allow backpacks (daypacks) in the hall?
Yes, backpacks are allowed. The watchword for attending and enjoying the Show is to wear comfortable shoes and to dress in layers, as the Show floor can get chilly. The Show takes up 10 acres in a convention center space occupying 3 city blocks. So, your backpack may start to feel heavy after a bit. Should that be the case, know that there is a coat check where you can check the backpack and your outerwear.
Hope this helps, and enjoy the Show!
