Amazing people pay for rooms when over and over I've recommended taking the short time to learn video poker(which is a win longterm in itself) and recieving all the comps that the hotels will offer you........ free rooms, food, beverages, and even cash in the mail.
For beginners, learn dueces wild and then play the game at ANY of the station casinos........and you will be good to go at any of their many locations in the valley............not to even mention others across the country.
Harrahs has hotels all over the country and are all connected to ONE slot card........having said that, you will be hard pressed to find 100+% games at Harrahs........but learning jacks or better at 99%+ is worth it for the comps.
I may be starting my own website in the near future where you will be able to learn to even take more advantage of what casinos have to offer.
