1) Why do you think there are three categories?
2) Obviously, Cat-2 is worse then Cat-1.
. . . Cat-2 is further away
. . . in many cases, some at the tabloe have to turnh around in ther seats
. . . the seats are not as desirable as Cat-1
3) Obviously, Cat-3 is worse than Cat-2.
. . . Cat-3 are out of the way
. . . in most cases there can be a pillar or post in front of you
. . . in many cases, you have to crank the neck to see
. . . in all cases, people at one side of the table have to turn around to see
NOTE: You will hear people say "We had Cat-2 (or Cat-3) and loved the seats. We couldn't tell the difference from Cat-1.". Let me assure you, they did not realize how bad the seats were or did not have an appreciation for good seats. It is like someone saying that they sat in the orchestra section for a musical or in the balcony, and thought they had great seats.
