No steps to get in; there are two staff-operated lifts to go up the two areas to get to the main room. The main room has graduated levels down toward the stage with a gradually-sloped step-free aisle along the side (e.g. you can access the floor at get right up to the stage, or stay farther back at one of the elevated levels)
The stage is pretty high, so might be hard to see if right at the stage (nose-level for a wheelchair user). Need to find a staff person to operate the lifts to access the main area and bathrooms.
One (maybe two?) wheelchair-accessible bathrooms in the area at the level of the first set of steps (i.e. you have to get a staff person to bring you from the main area down one level to where the bathrooms are)
