When are majority of the gentlemen leaving? Has anyone gone out & freelanced this week?

The important folks that various companies send out tend to leave thursday to get back in the office by friday morning. The average attendee might leave saturday to give them a night in vegas to cool-off, plus a night at home to unpack and get back at it by monday.

 
Having attended CES a few times, I will say that by friday you're exhausted, dehydrated, and generally done with being in vegas for much longer.
