My family loved it. The story to the show is somewhat corny, but the traditional dances are very good. The flame thrower is awesome. I got pulled up on stage, and got to kiss the guy during his Maori demonstration (it was tough, but someone had to do it) I ended up with most of his tattoo make up on my face, but it was so worth it (my DS was somewhat shocked!)
The food was pretty good too. DS (7 at the time) enjoyed pretty much everything, as did me and DH. It was fun. I can see how having 3rd tier seats might be an issue, however. The tables are pretty long, and there are two sets to each row (I think) So you could be quite far back.
