I'm part of the new Booking.com beta group, syncing over content (photos, amenities, descriptions, etc), and I'm enjoying it.
I noticed this list of "Fine Print" items in the Booking.com extranet, and it's a bunch of random hotel and COVID related stuff. See below.
I wouldn't care, but there's one called "guest must show ID and credit card at check-in" that is turned on for all properties. And this is showing out live on the public guest side. There's a big warning saying that ID/CC will be required when you get there. BDC also has a history of dropping in new hotel-type stuff like this. Now that you have content sync working, it would be great to be able to turn these off automatically.
