Buy an electric scooter or hoover board.
depending where your seats are there will be some walking however ask the ushers which area you are to minimize going accross the building. as far as walking to an event from your hotel, i would recommend an Uber, that is the easiest so you dont have to worry about parking and how far to walk.
Have a taxi or Uber drop you off at the front door. Other than that, I don't remember about inside the building.
