I went in 2005 and enjoyed it. (I know that is not recent.)
I would suppose that it probably lacked something in authenticity, but as someone that has never been to Hawaii, I really enjoyed it. I do think it would be well worth your while to get seats close to the front. You are not sitting indian style on a beach with 20 people. You are seated in a picnic pavillion that holds 200+ people. The food is really good, but not fantastic as it is being cooked for a lot of people at one time, and the dessert is not special. I would highly suggest it.
I do want to say this to the poster from Jacksonville, Alabama especially.
I'm originally from rural Northwest Alabama, and much enjoyed Spirit of Aloha over the Hoop Dee Doo Review. That is the opposite of most posters.
You may can relate to this...I've been to hillbilly shows, both local productions and at places like Opryland, and grew up on Hee Haw. I've seen hillbillies up close. Why some folks might even say ( I r 1 ). If you got that then ur2. So, Hoop Dee Doo fell kind of flat, not insulted, just unimpressed. Spirit of Aloha was a new adventure with a lot less hype and I enjoyed it much more.
