Can anyone explain to me the difference between regular Platinum, Platinum 5 Star, and Platinum Premium? What the benefits are of each if different. And what it takes to get Platinum 5 Star and Platinum Premium? We are pretty much Marriott people, Gold Level for a large part of the last 30 years, platinum for the last couple. We do sometimes stay at Starwood and boutique locations throughout Europe and were wondering if going after Platinum 5 Star and Platinum Premier is really worth it or even attainable. We like to know our goals and strive to achieve them(maybe that is impossible as I read comments on the Platinum Premier issues). We don't see much difference between Gold and Platinum except for the arrival gift at a few locations. We are retired and travel about 4 months of the year. We pay for our own travel...no more corporate travel(Thank Goodness) and are trying to figure out if we need to change strategies to get more bang for our buck. Thanks in advance for any advise one can give.
