Las Vegas: Skip the line of the club in the hotel you're staying in?

I'm staying at the Venetian in a couple weeks with some friends and I'm wondering about the lines at TAO: if we have room keys, can we just skip the line of non-guests and jump into the club? Or do we still have to wait in the VIP line? Or slip the bouncer a Benjamin? Or what? And does everyone need a room key, or can we have four people get into the club with two room keys?
