Tiers (aka Categories) refers to seating.
From another website:
Category 1 is located in the lower level, in the center and nearest the stage so you will be as close to the performers as possible. You won't miss a moment of the excitement with these wonderful seats. You'll feel as though you are one of the Polynesian dancers.
Category 2 offers tables in the lower level that are located on either the left or right side of the stage OR upper level tables that are located directly behind the Category 1 seating. All of these seats will give you and your family a great view of the entire stage area and you won't miss a thing!
Category 3 offers tables in the lower level that are located to the extreme far right or left of the stage, OR the majority of the upper level tables. You will still have a good view of the stage and be able to enjoy all of the excitement of the authentic Polynesian dancing.
---------------------
I might add that you can end up behind a pole, depending on where your seat is. Also, based on the time of year for your visit, the show can be H-O-T.
I always tell folks they should try this one out at least once, but if it comes down to a choice between it and the Hooop De Doo Musical Revue, go for the HDDR. It's just better all the way around. My preference, of course.
