Cash Games at Rio running all night long?

[Headhunter13]

Do the cash games at the Rio run all night? Last year, I was out there during the Main Event, and I thought that they closed pretty much when the tournament closed, and didn't start up until noon (and sometimes later) the next day. I'll be out before the Main Event and was wondering if they run all night. Also, is it as chaotic as last year with whiteboards/floor that aren't always up-to-date and it was often easier to get a seat by hovering at the table you wanted to play.

Thanks,
