I don't get it, I went to every Microsoft Professional Developers Conference from 1995-2005 and I never saw any partying (well, there was that one visit to Universal Studios that was pretty cool). I missed out!
Almost 10 years ago work sent me to TechEd 2002 EMEA in Barcelona. I remember a party with Cirque du soleil (or a similar) troupe, and a Ballmer-like break dancer. Everyone was driven over to the event at one of the former Olympic venues. There was booze and loud music but it a fairly good event even if you weren't drinking.
