At my organization, all of the meeting rooms were set up as "people" rather than as resources.

I want to correct this, but the room schedulers like this configuration because they can open all of the room schedules side-by-side and see what's going on at any moment.

If I re-create the rooms as resources, is there any way to see the room schedules in a side-by-side view like that?

Thanks, in advance!

In windows you can go to Calendar/Actions/View Group Schedules and place any resources together to view at the same time.
