The Pantages is HUGH and WIDE .... I can almost promise you that you will feel like you got a "bad" seat if you don't buy the premium seats.
Avoid the sides as much as possible... center in the last row is better that half way down on the sides.
Mezz for the most part is pretty OK.
Good Luck. Enjoy.
Walk on, walk on, with hope in your heart; and you'll never walk alone.
