Oh, also always have a cell phone on you at all times, put it on the highest level possible if you are going to be in a noisy place, but put it on vibrate when you are in a panel. I had my cell phone go off during one of the guest panels a couple years ago, it was so embarrassing. And you should always tell a friend or someone where you are planning on going if you are going by yourself. I don't know how many times I was in a group that wanted to go do something but couldn't because a couple of us had wandered off and we didn't want to leave them behind.
