What time to arrive at IBJJF Master Worlds? (Planning flights...)

Hi there! I'm competing in Master 1 at Blue Belt. The pre-schedule (http://ibjjf.com/championships/world-master-2017-pre-schedule/) says Blue Belts are every day - Thurs, Fri, Sat. I'm trying to buy plane tickets ASAP since the McGregor/Mayweather fight got announced for the same weekend.

Anyone have any idea when I'd want to make sure I arrive in Las Vegas? I have no idea how they usually schedule this tournament...
