Got mlife Platinum this year for the first time and had a quick stay at Vdara last month. They gave me the letter with the Platinum Experience options (shark reef, Secret Garden etc.) but I did not use it. Going back this month but staying at Planet Hollywood. I still have the platinum experience letter and it does not have any date on it - can I use that letter to do one of those things on this trip? Do they check when you show them the letter that you are currently staying at an MGM property?
