What is the one piece of advice you would give about attending AXPONA?

Greetings all - For those of you that have been, what is the one piece of advice you would give to someone attending it for the first time, or to any audio show for the first time? 

Planning to to attend all three days. Riding the elevator to the top floor and taking the stairs down, is one thing I’ve read, and of course it makes perfect sense. What else? Thanks in advance for your responses.
