How to hide or prevent booking a specific room?

Hi
We are setting 4 rooms aside to be advertised in booking.com. As such, we don't want them to be available for the public to book... BUT, we do need to be able to enter bookings in the backend.

What do you think the best solution would be?
Thanks

Thanks, that's a great idea.

Hi
It's sort of working...

I have added a customer group called 'booking.com', and set a specific tariff assigned to this group.

Logging in as a registered user, I don't see the tariff on the front end, as I would want. But when I try as superuser, or my colleague as administrator, to add a new reservation in the backend, we only get the public tariffs showing in the drop down menu.

If I change my customer group (in my customer details) to 'booking.com', then I only get to see that tariff, not the public ones, in the front end and backend.

I don't understand why the users who have access to the backend cannot see all tariffs? Must they be specified as Solidres admin? Where and How?

I may be missing something obvious, but have gone in circles so much that I'm not seeing clearly any more.

Unfortunately my subscription ran out a few days ago, so I'll have to leave it.

C'est la vie
