When you are scheduling a meeting with someone or multiple people, please try to book a meeting room in advance. When creating a google meet invitation, on the right you can choose to add guests to the meeting, but you can switch the tab to ‘rooms’. Here Google Calendar provides you with a list of rooms that are available at your chosen time slot. Click the room of your choice and its done! When you’ve booked a room and encounter colleagues occupying the room at you slot, you can kindly ask them to leave, since you’ve booked the room.

Per room you are able to see the available resources for that room, like a TV, webcam, microphone or whiteboard.
