Vegas Vacation

I’ve seen some pretty good Las Vegas trip deals out there through run of the mill travel sites like travelocity, orbitz, etc. but I’m sure there must be some even better deals on some corner of the internet or through a travel agent. Has anyone had any personal experience and gotten a really good deal on a flight and hotel or some other package trip to Las Vegas? If so, please share (any other tips on saving money at casinos or on show tickets and dining would be welcomed as well). I might be going in the Fall for a wedding and to visit relatives.
Thanks afore.
