The low room rates are for mid-week stays (boo) in a deluxe king room but it also throws in $25 daily dining credit, two VIP nightlife passes to the Playboy Club ($100 value) and two spa entry passes ($40 value.) Those are some pretty good incentives and they just happened to coincide with our mid-week trip to Vegas in a few weeks. So we booked it.
You can check out the available dates for the $69 rates here. Early and mid-May seems to be the time when the most $69 rooms are open but there are plenty of dates in April, some in June and less in July.
