In addition to listing the location of the activity on the calendar block (so you can see it without opening the activity fully, as has been suggested by others) it would be helpful to be able to filter activities in calendar view by location. Previously we used 'ghost users' for each conference room and added them as Attendees to facilitate scheduling and easily seeing when each conference room was booked vs available, however, now that our subscription model changed to being charged per user we have had to deactivate our conference room users and need an alternative way to be able to easily see and filter by location to ensure we are not double booking our spaces.
