answer:I haven’t been in years. If F means row 6, that typically is not considered an ideal seat, I am assuming it is not priced as high as the “best seats in the house.” I like to be at least 10 rows back in any large theatre. 20 is better. Hopefully someone who knows, or remembers the theatre seating well, will answer also. If it is a last minute and these are the best seats to choose from I would go ahead and buy them.
