The biggest, best tip I can give you for getting the most enjoyment out of TechEd 2013 is become part of The Krewe. The Krewe is the community entity for TechEd. It's a great bunch of folks to get to know. If you're a TechEd newbie, check out their web site to get news on TechEd schedules for both daytime and nighttime events.
