Some more tweets exchanged with Marriott Twitter customer service. I am wondering if they have rerouted this conversation I am having to the local Greek hotel staff (note the "we" in their replies):

@MBonvoyAssist: Mr. Eggert, The Greek Ministry of Tourism has decided to proceed with a regulation that gives tourism companies the opportunity to compensate their customers by issuing an 18‐ month voucher. You may continue to communicate with the hotel directly. We cannot override what has been decided by the Greek Ministry. Thank you.

Me: So you are not going to honor your publicly posted COVID policy?

@MBonvoyAssist: Unfortunately, as it is a regulation by the Greek Ministry of Tourism, we are unable to override the regulation. If you would require further assistance for this matter, please continue to communicate with the hotel team as they are the best team to help you.

Me: I made a booking on Marriott.com. How does Greek law apply? Marriott is not a Greek company. And the voucher I am offered is not even a Marriott voucher.

@MBonvoyAssist: The Domes of Elounda, Autograph Collection is a Marriott property located in Greece, so we are guided by the laws of this country. The local government has decreed that hotels in Greece have the option of issuing a voucher to be spent within 18 months effective from the voucher issuance date, for those bookings made between February 25 and September 30, in place of a monetary refund. We hope this clarifies.

Me: Yes, you have the *option*. But your published COVID policy promises a cancellation with no charge, i.e, a refund. A voucher that isn't even usable Marriott-wide and which I cannot cash out for 18 months is not a refund. I'd like to again ask why you are publishing a policy that you then do not adhere to?
