Whenever I have gambled at any of the Caesars properties (Caesars, Harrahs, Quad, Paris, Flamingo, Rio, Planet Hollywood, Ballys), I have gotten offers from all of them no matter where I spent time and money....assuming I wagered enough for them to even notice. Of course all of the offers weren't the same since some of the properties such as Caesars are considered a little more upscale. So, whereas I might get comped room offers from Ballys or Harrahs, I might only get a nice discount on a room at Caesars. Anymore these offers aren't mailed to me. I either receive them via email or can check my offers online.
