I just saw a post on Facebook MyVegas friends about redeeming rewards and now I'm very confused. I thought you could purchase 3 rewards per 30 days according to page 2 of the reward. So basically, I was planning my Vegas trip for June and since I'm 90 days out, I thought I could get 3 rewards each month before I leave and have 9 rewards. I didn't realize that you could only use 3 per trip? Is that true?
