On the positive side, I think the little bit of chaos that came from the natural disorganization of a "free conference" helped me get in to a few rooms despite the general overcrowding, it also made me miss a few talks cause I could never get a grip on the wacky room locations and numberings.

I have this unsubstantiated fear though that having the conference more orderly may actually make things worse.

I liked how some people brought their kids, that was great.

(I found the anti-cash vibe in Brussels outside the conference pretty fucking annoying though. Metro machines that take coins but have no cash slot? What is this bullshit?)
