If you go to South West.com via this link you can book the Orleans for $40 per night for those dates, which is a real bargain over a weekend. It is supposed to be a very nice hotel, and gets great reviews, although I have never stayed there. They have a shuttle to their sister hotel, the Barbary Coast, which is next door to the Flamingo. So, if you don't mind being off-strip, I think this might be the way to go. With the money you are saving you can buy them a really nice wedding present! :)
