I know we talked about HET expanding Total Rewards to include non-gaming activity but it is now active in AC. You can earn 1 reward credit for every $1 spent at Harrah's hotels, shops and restaurants, spas, etc. Just show your card when you make your purchase or check out of your room (if you are paying for your stay). For every $5 spent, you get 1 Tier credit.
Program is available at all properties except Rincon and Chester.
