I am a huge fan of Wagerworks now! Just returned from Vegas yesterday, and had no trouble redeeming my two free nights at the Mirage, and a buffet for two at the Mirage. They treated us better than the average guest, with VIP check in and front of the line at the buffet.
Here's the deal... go to wagerworks.com. Choose any hotel ( you can redeem points irregardless of what hotel you are playing games at. ) Register. Choose "play games". I play 50 line video poker, and get a point for game of video poker I play. When you have enough points, you can redeem for prizes like free stays, buffets, shows and upgrades.
It took me about 4 months to earn my stuff. My husband also plays on a seperate account, and we do it while we watch TV. It does get boring, but when I did the math, I am getting more for my clicking than I do at Creations and the like.
The site is owned by the MGM Mirage family of hotels, and the prizes are all for their properties. MGM, New York, NewYork, Treasure Island, Mirage, Bellagio and their casino in Biloxi. I feel safe that I won't get "messed over" like we do at other sites, because it is owned by a huge company that is doing just fine.
I am seriously considering dropping some of my more time consuming reward sites and concentrating on this one, since we go to Vegas twice a year.
