I've been platinum for about 5 years now. I stay at the JW Marriott at the Mall of America 10 to 12 times a year. I never get out on the concierge / executive level, but my coworkers who are only Gold get that level almost every stay and they don't travel as much as me. Can someone please explain why they get upgrades and I don't? I'm really questioning continuing to work on making life time gold.
