Box C at the Ambassadors Theatre
Box C is the only Box: four fixed chairs, up on the Circle's side wall over its front five rows. It isn't always on sale, and for most people the Stalls are the better buy.
What you see
The view is from the side, but the Box is far enough back to see the whole stage from most of its chairs. Chair 2 is the one to have: it sees the most of the stage and you don't need to lean. Chair 1, nearest the front, has the most restricted view, and chair 3 misses about a fifth of the stage at the side and has very little legroom.
Is it worth the money?
For Paranormal Activity, Box C is in the third price band. For the same money you can have Stalls row A or row M, both facing the stage, or the first three seats of the back row of the Circle, which have more legroom. One band up, the pairs of seats at the ends of Stalls rows C to K are head-on too.
Where the Box does make sense is if you'd rather have a small private space for two or three of you than the best view, or you want a bit more legroom than the Circle seats at the same price.
FAQs
Is the Box worth it at the Ambassadors Theatre?
For privacy, it can be. For the view, no: it's side-on, and Stalls row A or row M costs the same and faces the stage.
