The car parking aspect makes central London venues difficult, both because of fearsome parking charges, and because of the Congestion Charge on every car (which includes the tech crew, who will have gear to bring).
You have to consider what will be seen behind the interviewees when on camera. Function rooms usually have to double as conference / seminar rooms so it may be difficult to find a section of wall that does not have trunking, fire notices, switch boxes and other clutter. Will drapes on rails be brought in to provide a backcloth? If so, does the room have sufficient width and height to avoiding shooting off on a wide shot?
If the room has windows to the outside, consider where the sun will be as the day progresses. Will it shine in the interviewees eyes? Will a sideways sun give big nose shadows? Will the sun dodging behind clouds give a constantly changing exposure for the camera, making continuity difficult? Don't rely on blinds, the sun can still creep through, with the slats leaving patterns.
If the room is to be lit totally artificially, is there sufficient height to get in tall lighting stands, thus avoiding having key lights in people's eyes? Will there be sufficient space behind the interviewees to put in back lighting (essential for good portraiture)? Is the interviewer to be seen in shot? Full face? Over the shoulder? More problems when putting in lighting. Don't rely on the (normally overhead) room lighting - You can get deep eye socket shadows and there are aspects called 'colour temperature' and 'colour spectrum' from domestic/commercial lighting which can give most unpleasant skin tones.
A function room will normally have stackable banqueting chairs. If these are to be 'relaxed' interviews, will armchairs / easy chairs / sofas have to be provided from somewhere? Make sure they are not made of a material that 'squeaks' when the interviewee shifts in his/her seat. Avoid swivel chairs like the plague (unless you are dealing with television professionals who know how to sit still unless changing shot).
Function rooms are rarely soundproof. Where is the nearest airport? Where is the nearest main road (emergency vehicle sirens)? is the corridor outside on the route to the kitchen (catering trolley noise)? Will you be able to rig a red 'recording ' light outside, and will you have enough crew that someone can be stationed outside the door to stop entry during recording?
If there is a string of interviewees, then you will also need to book a room as a Green Room with tea/coffee on hand. You mustn't expect people to wait in the room where the interviews are taking place. They want to chat (quite naturally). Don't let them get to the bar until
after their interview has taken place.
Lots of things to think about!
