It's a convention center - a huge, ginormous Vegas convention center. Seriously - its massive. From my Mandalay Bay hotel room to my booth in the Exhibit Hall was about a 3/4 mile walk so you'll get your exercise.
On the plus side - there are lots of lounge-y places to sit and check messages while between meetings. The restrooms are plentiful and clean. There are rooms galore to accommodate any size group or function.
On the minus side - ok, I know it's Vegas but really....$150 charge for someone to vacuum my 10x10 booth...per DAY? $75 to have three relatively small boxes moved from the 1st floor to the third???
My conclusion is that I am in the wrong business.
