Parties with wheelchairs were seated at the back of the first (orchestra)section. There is an aisle that runs between the orchestra section and the mezanine section. It does give a fair view of the stage and off-stage action.
we always sit in the front row when we can. otherwise, the 2nd or 3rd row, on the aisle near the left of the stage. This way we are sure to have interaction during the parade.
