I'm sure the answer is posted somewhere, and I have looked at the Total Rewards website and other internet site...but I am by no means a super sleuth. I have 18,000 Total Rewards reward credits. My understanding is that this translates into $180 that I can use towards food, drinks, entertainment ect. Can I use the 18,000 Reward Credits for $180 of gaming? If so how? Tables/slots only? Will I get Tier Credits and Reward Credits as I use it for gaming?
