Having read this forum I thought I would check the situation with the Bangkok Sofitel where I have a one night booking in April.

Our Thai overland journey has been cancelled, there's a 2 week quarantine at the Thai border for people arriving from Hong Kong and then a 2 week quarantine for all of us returning to Hong Kong. So it's impossible to go to Thailand. I was curious what the local Sofitel would say and would the fact that I have one of their group's new Diamond cards make any difference.
The reply was, in effect, "Sorry, but thank you for your loyalty. We can let you change your booking to a date within 3 months of your original booking, after which we will keep your prepayment".

It's something I suppose (at least in the short-term if you believe this will all be over by July - living in Hong Kong it is clear that it will not be over by July as a global crisis) and it's just $200. But as I see from this helpful forum, most hotel groups have published a clear, reasonable and future business-focused change and refund policy. But not Accor, which seems to believe that I and others will just go back to booking with them through force of habit. In fact reading the forum tells me that I've been right in my sneaking suspicion that I couldn't care less about Accor as a hotel brand, it's the Sofitel St James I likeas a hotel and stay at maybe 60 nights a year, which is what gets me the Diamond status.

The rest of the Accor group has been pretty useless when I've stayed with them and seems to care about me as little as I care about them! As the saying goes: "a fish rots from the head" because Accor HQ appears to have adopted a head in the sand approach to the problem - both its magnitude and its duration - allowing hotels in their group to say and do what they like, making up unofficial policies as they go while at the same time showing me that I should return to staying at the Mandarin Oriental in London rather than the Sofitel St James, just to feel good about not giving money to a hotel involved with a useless and customer-unfriendly management company.
