iCalendar allows you to view the booking calendar from any calendar software that supports iCalendar, e.g. Calendar on the Mac or Outlook on Windows.
When you go to the booking calendar, click on the small calendar iCal button. A popup with a URL will open. This is the URL to the feed that displays all the resources.
To get a feed for a single resource, select the resource from the drop-down and copy the new URL below.
You can setup a tablet in front of their meeting rooms and use these feeds to display the booking there, which we have found to be very effective. Or, check out our Meeting Room Display Add-on.
