Well, will your kids, actually be willing to get up on stage?
If they would not get up on stage, then, that aspect of it would be useless.
And, are ALL kids in the audience chosen to go up on stage??? Or not?
Traditional Hawaiian dancing, ie: the Hula, IS Hawaiian dancing.
"Fire" Dancing, is not typically Hula, dancing. Per Hawaiian Dancing.
Fire dancing, is a known Samoan tradition. They are famous for this. Not Hawaiian per say. Hawaiian culture does "Hula" dancing.
These are 2 completely distinctly and different, Polynesian cultures.
The Fire dancing is done because, it is very visually showy.
The traditional Hula is also. These are 2 completely different dance styles.
The "Hula" is NOT "fire dancing."
And Fire Dancing, is not the "Hula."
Per food: If it were me, I would opt for the good Luau food. And the traditional Hula dancing.
But the other one, per the kids and their participation, would be fun. IF the kids were the type that would participate. Thus, you can get photos of them doing it.
Real Luau food, is authentic Hawaiian food.
Some others may have more foods which are made more for mainstream palates. Thus, the rating of the foods, can really vary.
And, most Tourists, are not used to Hawaiian Luau food. It is good. But, it is a culturally different, food. But because most Tourists are not used to "Hawaiian" Luau food, they either will think it is good. Or not. Because their palates are not used to real Hawaiian Luau food.
So, the question is: would YOU know, if the Luau food was good or not?
Unless you have had Hawaiian food before, you would not know if it is good or not. Per the Samantha Brown, review.
A fun part of traveling & visiting Hawaii, is trying the various local foods we have here. Including Hawaiian foods.
And some like it or not.
Some Tourists come here, and still, go to eat at McDonald's for example. Some others, will go and eat the various ethnically diverse foods we have here. We are known for our very diverse ethnic foods.
But either way, picky eating kids, probably will not eat. Because it is not what they are used to.
The Luau prices you stated, are typical. Average. The norm.
