My Nitty ways with Vegas
First some basic notes.
If you like to stay and eat at Caesar's properties but only play occasional table games when not at the poker tables, get a Total Rewards
visa! If you charge $5,000 to the card during the year you gain platinum status. $10,000 gets a VIP pass. Platinum gets you free parking in the garages and you can avoid the massive check in lines. Plus every time you charge you earn points that can be used at Caesars properties for just about everything. Every time you use your card, your points expiration date get updated to 6 months after that date. So, if you go only one time a year to vegas like I do, it's nice to never have points expire and get extra perks.
Recently I have found offers for comped rooms at a number of properties. This past trip I stayed at the Flamingo for 5 nights, Sun - Fri, comped (all I paid was $170 resort fee). If you aren't picky about rooms, the flamingo has a nice mid-strip location.
If you are not picky, I have found deals at Harrah's, Flamingo, and Bally's. At different times of the year I have seen comp deals at PH, Paris, Rio, and The Linq too.
Get on property mailing lists and watch for those sales. Even when you have already booked keep looking. Caesars properties are very willing to change one or more of your night's rates without having to completely re-book. Golden Nugget (where I like to stay downtown) will usually make you re-book. So, I just book the new better deal and cancel the other reservation.
This year I booked a Carson Tower King at a great deal (as far as the nugget goes). When I arrived I was offered for a little more a night a Gold Club Room (second from top floor in the Gold Tower--closest to PokerRoom and Fremont Street). For the 7 nights there I spent a total of $715, Friday through Friday.
