I am a Platinum Elite member and have "lifetime" for my expiration date. As you can expect I stay at lots of Marriotts and have for many years. What I would like to know is some hotels treat me very nice with very nice upgrades and some do not. Are there any guidelines that they go by that I should know about? I truly do appreciate the nice treatment, and don't want to abuse it, but I also spend a lot of my money at these hotels so a little extra is appreciated.
