So, I'm in Vegas for work ( I work for a tech company based in Silicon Valley). We have 2 or 3 events a year in Vegas. Since 'home office' is the trend in the USA, we hardly ever see co-workers, and when we do...we bond. So, 1 day in Vegas = 3 days.
First, you are in all day sessions from 8am - 6pm. Then, you are in team dinners from 6:30 - 10:00....than, (and you can wimp out), you are bonding with other friends from 10:00pm - 3:00am. Than you start again.
This isn't meant to be a whine, only the way your body responds. Vegas is lots of fun, in small does.
Hope my friends in Bangkok are getting drier everyday.
