Appointments for room reservation

I want to install Appointments for an organisation that provides spaces in one building.

It is one person doing the reservation and multiple rooms that can be used. There is no payment involved.

The complication is that not all the rooms are available during the same time and timeslots. And that I cannot create different users to attach the rooms to, because than I would need fiver different email adresses.

In the tutorial I saw: Reservations for sports fields, tennis courts etc as a possibility. So I figured this would be done in about the same way. But I don’t see how.

And I wonder if it will be possible to handle all this on one page with one calendar.

I am curious if this can be solved.
