I posted these on BLAUGI  (the AUGI blog) way back in 2006, but they still apply today. If you are heading to AU, here are some suggestions.
I have been to a few of these events and have some advice for those who may be going the first time and for those who want to get a little more out of the event.
Dress casual – business casual at best – you may also see some very sloppy dressers – Whatever you usually wear to work will be fine, unless you wear a tie – lose the tie.
Dress comfortable – these will be very long days – you may be walking a lot.
Bring plenty of business cards – pass them out – exchange them with others – give them to vendors
Take a lot of notes – Don’t expect to remember anything – by the end of the week your head will explode.
Talk to as many people as you can – Fellow users, vendors, teachers, Autodesk employees, etc. Don’t be afraid to introduce yourself to strangers. Fell free to join others at a lunch table. Never eat alone and never stay silent if someone is sitting next to you.
Get the Handouts – Handouts may be made available for classes. Handouts will be posted on-line after the event also. So if you miss a class or have two that you really want to attend at the same, you can still get the handout.
Be prepared to eat – a lot. Breakfast, Lunch and sometimes dinner is provided in ample portions.
Have Fun – take a break from the event if you need to rest. Get away from the crowd or take a power nap.
Expect to Learn A Lot – This is the best training in a wide variety of topics in a short amount of time.
See you there…
