Susan, it's no help in your question, but did you see my nearby comments,

I would respectfully suggest that it is not a good idea to use a consolidator site like Hotel dot Com when you are dealing with possible closures. Some consolidators have a nasty reputation for cancelling bookings when hotels withdraw some of their offered rooms. But my main point is that you harm the reliability of your "information" when you interpose a third-party.
I also prefer to be the actual customer, in case I need to make changes, or want to change the room they offer me first. Businesses do tend to treat people paying money directly to them a little better. Again, there are special conditions with your search. For example, maybe saving 20 Euros on a consolidating site is a poor exchange for losing direct control of the booking (?)
