For meetings that go on over several days, only one meeting room exists in time and space. That room has seeral rows of tables and chairs, a white projection screen and no windows. Sometimes there are microfones on the tables, sometimes they are located on the walkway between the tables. Sometimes there is a carafe of water on every table, sometimes you can get water in the back of the room. These things change from meeting to meeting, but that is only done to make the participants think, they would sit in a different meeting room than last time. But that is not true. It is always the same.

Usually outside the meeting room the sun is shining. That's why there are no windows. An urban legend reports, that there once was a meeting room with a window front, but the curtains were closed all the time in order to make the projected picture of a laptop screen visible for the participants.
