Good luck, eefor jfp.

Sometimes finding the right person to handle an issue via telephone can be tricky. If calling doesn't work, you can use the "Contact Us" form on the Marriott website as a back up. As your first line in the Comments box, enter something like: "Please forward to the hotel."

In my mind, this is the best way to asynchronously communicate with a hotel. Email can get ignored or deemed SPAM by a computer. The "Contact Us" form gets entered into Marriott's system. That means it is tracked and hotels are required to respond within a set time frame.

It can take a few days to receive a response via telephone or email. But, you should definitively get one. Still, I think calling is the best method.
