I am a Platinum Member with Marriott and just returned from Paris and London. I did a quick 6 day trip with my teenager daughter to reward her for 3 years of great grades in High School. I tried to stay at the Marriott Champes Elyses for 3 nights using Standard Rewards. Even though the hotel had plenty of rooms,I was unable to get Reward space. The Marriott Platinum desk said they could do NOTHING for me.(except pay 50% more points) I then called Hilton Diamond Desk and they said even though the Paris Hilton had no Reward rooms available,they would get me a room. They did! I then tried to get a room at The London Marriott County Hall for 3 nights. No Reward availability,even though they had plenty of rooms for rent. The Marriott Platinum Desk said they could NOT HELP!(once again unless I paid 50% more points) I then called The Hyatt Diamond Desk and even though they had no Reward Availability,they got me a room at The Churchill using Standard Rewards points. I have been life time loyal to Marriott;many years as a Platinum. It takes me MANY more nights to attain Platinum level with Marriott than Hilton and Hyatt. What am I doing wrong? Is this the way Marriott treats their highest level members. Just voicing my frustration. God Bless.
