I sat in the center of front row on stage right (audience left), along the aisle. Incredible experience! No water bottles, no candy, no bathroom break - so definitely go to the bathroom before the show begins. I put my coat and bag underneath my chair, plenty of room there. I had unwrapped cough drops in my pocket just to make sure I didn't cough during the show.
The stage seating ushers are very clear in instructions and give you the spiel twice before you sit. And one of them is the designated usher that will sit off to the side and help direct you if for any emergency reason you need to leave (obviously cannot return).
Highly recommended, it was so immersive.
