I booked an Advanced Purchase reservation with Marriott at the Ritz Carlton in Istanbul on December 3 for 8 days, April 29 - May 7, 2020. We found out yesterday, December 8, that we could not make the trip, and I tried to cancel. I was told that the entire booking was not refundable because the day of the booking was December 3, and I needed to cancel within 24 hours, i.e., by December 4. Unfortunately, I did not know until yesterday, December 8, that we needed to cancel. They did offer a date change option, but I have no idea when we will be able to plan another trip - it may be 2 years or longer. I feel that the hotel would not lose any money on our room because they have a long period of time (today through April 28, 2020) in which to rent it out. I am a lifetime Platinum Elite member, and my wife and I stay at Marriott whenever possible, both for vacation and business. Is there anything that can be done?
