Renting a house/condo for a week in Vegas?

[BigBaitsim (milo)]

A dream come true! The wife, having listened to me talk poker for the last year went on a three-day trip to Vegas and found she LOVES the game. She is insisting on a week-long trip in September. This time, we will be taking the kids (and a college girl who sits for us sometimes) and are looking at two connecting hotel rooms. It seems like a condo or house might be cheaper and a better arrangement. We've done this at the beach, but don't know if Vegas works this way or not (other than timeshares, which seem to have poor EV).

Which brings up a question, who are more annoying in Vegas, the timeshare guys trying to get you to come see a 2-hour presentation, or the guys handing out the "girl to your room in 15 minutes?"
