These are non-specific seats. When you purchase a general admission ticket, you are assured of a seat but not of its location in the theatre.

When you purchase a premium ticket, you will have a reserved seat with your name on it and it will be located in the front row of either the floor section, the fist row of the first elevated seating section or the first row of the back elevated seating section. In other words, you won't be looking around another patron to view the performance.
