I agree they do serve different purposes, and now Hyatt has an offering for members to have a fun vacation on the Strip without needing a car to get anywhere exciting. Vegas prices are really all over the place though; I got a room at Venetian for a couple of weeknights in October at the Venetian for ~$90/nt (after taxes, before resort fees) on Hotwire. While I don't think they'll offer rooms at those prices on more transparent booking channels, there's a good chance of finding deals on off-season weeknights.
