The stage and auditorium are all on one level. The seats are normally arranged on stepped rostra in rows facing the stage; if you wish to re-arrange them you will need to allow 1-2 hours depending on the arrangement and the number of people you have available. No alterations are to be made to the rostra or their fittings. In particular, they are not to be disfigured, nor should anything be nailed, screwed or otherwise attached to them. Under no circumstances are the seating rostra to be used on the stage or as part of the set.
