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.

Great advise by everyone.
If you like a product exceptionally well, take a pic or 2 so that you can remember what you really "fell for". This is for future buying decision.
I also suggest to keep Shazam OR Sound Hound handy. That way you are automatically keeping track of the new music you liked at the show. I picked up 50+ songs over a 2 day period and created a Spotify list.
Look out for fellow audiogoners :-)
Great advice all.  Thank you.  I did a real newbie thing.  I excited posted my query, then realized that I had not searched the archives.  I did so, and found several threads on this topic.  Still, there is some new advice here and I appreciate it.  I am really looking forward to the experience.

@testpilot - if I only have two out of three of those things, what will that get me?
Pull out the Rolex, comb your hair and wear a sports jacket - that way dealers and exhibitors will give you the time of day.

@kcpellethead, based on your user name, you could always purchase a toupee for the weekend :-)  Enjoy the show!
