I had gifted a certificate in the name of a person who is joining us on a vacation to Mexico, but is flying out of Ohare on a very early flight later in the week. Given I was going to be out of the country, I had the Marriott Rewards category certificate put in her name and have a paper certificate for her. The reservation, in her name, used to show up online and it said it could not be changed or modified online and that MR had to be contacted to make reservations changes or cancellations. Tonight, it is telling me an e-certificate has not been ordered and will be auto-ordered soon, if I don't modify or cancel the reservation. I already have a paper certificate that I've already purchased with points, in my possession. It no longer says the reservation can only be modified or cancelled by calling MR's 800 number. Of course MR is not open at this hour. The reservations desk indicated to me it was a problem with the website and referred me to online support. Online support said it was a reservation made over the phone and therefore didn't involve them leaving him with only view access to the reservation, so they couldn't help. He referred me back to Marriott Rewards.
I'm sure this saga is to be continued.
