Okay, we just got back from Las Vegas December 23rd.... we are planning another trip in March and another one this December. Question is, on many of the rewards it says *limited to 1 per myvegas player* Okay, so does that mean it's a once in a lifetime thing? Or once per 30 days, 60 days, once per year? Unclear on when and/or if we can redo any of the rewards. Any knowledge would be great!
