You can't win with us IT guys, can you Victoria? 
Thanks for giving us a workaround for these crazy times. A few design change requests of my own:
- Our Facilities team would like to have single occupancy rooms available to be booked but only for a certain period and only for one person. E.g. The room is available 8AM-11:30AM. If a person books the room any time (let's say 9:11AM), the room needs to be scheduled from 9:11AM-11:30AM. This is to ensure people's safety as they are allowed to remove masks in the room, and air is circulated only a few times a day. Right now I don't think there's a native way in Outlook to do this.
- ChristianSchindler they're part of the way there. In room lists in OWA you can limit your meeting to only include rooms with a specific capacity. But I agree, warning users about cramped rooms would be a benefit.
- Pictures/maps/3D visuals of the room. At a minimum, allow admins to control if end users can upload pics of the room. Could prompt the users to upload when they are in a meeting in that room.
