The rooms have now been restored and when the new display is ready, hopefully before Easter (though this is still to be confirmed), they will be open to groups of 20 at a time with no extra charge on the entranceticket.
Benefits vary by status level, but include early entrance to the arena, exclusive ticket window and concession lines, pre-sale ticket priority, on-court photos with the team and many more such perks.
The mark of a true fan is to travel to a stadium without means of admission, hand over the next year's housekeeping to a tout and receive in return a forged ticket that will be rejected at the entrance.
