Thank you for being courageous to post your disappointment.
Recently, I had to renew my automobile insurance policy and came to realize that I've been doing business with Marriott ~longer~ than I've been a policyholder with my present insurance carrier. When I call, the insurance agent never fails to thank me for insuring with them for 24 years. During this period, insurance premiums have not dropped. Nor is there any expectation that they should. If there's any reward, it's a good driver discount. But the reward mandates my active vigilance everytime I'm behind the wheel. I wouldn't consider switching providers because my carrier's service is extremely attentive and responsive when I have a question about coverage or an insurable event occurs.
The parallel to Marriott, sad to say, is less striking.
Postscript 4/14: I'm delighted to eat my words. Yesterday I tried to rebook a reservation for my daughter on points and ran into 'capacity control' issues that stumped Platinum Elite. The Elite line required the GM's approval to do a "Platinum Overide". Happily, the reservation is booked using points, my daughter is upgraded to an oceanfront king room and I'm a hero! Hooray for Platinum Overide.
