Conference Teams Rooms

Currently we have 5 conference rooms, all utilizing Teams Rooms with their own email and license and calendar. Right now our admin team can see and approve meetings via their calendars, but in a few months we will be moving into a new building, and they've allocated 14 conference rooms in total. We've already got the systems and rooms planned out, but we are wanting to accomplish 2 things. One, the admin team wants to have a single place where they can visually see all the conference rooms and their bookings, without having their calendars cluttered. Second, we want to be able to have displays in break areas and reception areas that show all the conference rooms, their bookings, and even a floor plan displayed of where each room is. I've been looking into a few third party apps but would like everything to be in one place if possible.
