Here are some of my tips on how to make the most of the week at TechEd.

Make a session plan.  Know your entry and exit points.  TechEd is sold out.  Not only that, it is overbooked.  Expect to be sitting in the aisle if you aren't clear about which sessions you are going to and how to get there.  Spend some time learning the floor plan on the first day so you can get between rooms without getting lost. 

Don't stare too long watching the PowerPoint slides.  Every attendee is going to get a DVD with the slides and audio after the show (it will likely be on the web as well), so don't cram your schedule too full with sessions.  Pick the key sessions to attend, you can watch the others later.

Connect with people about the technology.  Instead of going to the breakout sessions, make sure you spend time in the Cabana areas and the Community Lounge.  The Cabana areas are small presentation areas where you can 'heckle' (well, ask questions and interact) the presenter.  The Microsoft stand in the Exhibit Hall has   many key people from the product groups at the event.  They are here to meet you, answer your questions and help you understand the technology.  Take advantage of this chance to have one on one conversations.

Speak to the Presenters, Authors or Regional Directors you see.  Don't be afraid to approach these people if you see them.  They are at the event to answer your questions and find out about your experience.  Use them. 

Focus on questions you'd like to have answered and areas of knowledge you'd like to improve.  Aside from the above, I think there's also a RIO networking area where you can go and find experts who can answer your question.  There are lots of key people from most of the Microsoft teams at the events and they are here to talk with you.   Spend some one on one time with experts rather than just sitting in the audience.
