Attending an audio show

For the audio show veterans: what tips or "strategies" do you have for attending an audio show? In other words, how do you maximize your time there and still make it fun and spontaneous? I've been going to one for five years now and I always end up with stuff I didn't get to see or forgot to see. I do make a list of room I want to see. When I get hungry and I go eat I feel like I'm wasting time. How do you pace yourself? Do you follow an itinerary? I think the answer is staying overnight but that's for next year--
