the reviews and experiences at ohana range the full spectrum. If it is something you are interested in, give it a shot and see how it works for your family.
Where you are seated will make a difference. All the games and activities occur primarily on one side of the restaurant. If you are on the other side, your kids can join, but difficult for you to watch.
Your server also makes a difference. I will not dine there again. The last 3 trips were progressively worse. I used to love Carnivore night (as we called it).
The last time we were there, we dined with friends who really wanted to go there. Our server was horrible, the shrimp were mealy, the sausage inedible and the steak grisly. The service was beyond bad.

Trying to get the different meats was not easy and getting them back was an exercise in futility.
There are way too many places that want me to come back. I think it is a matter of the place has die hard fans and a reputation that brings in the crowds and they don't have to try hard and they don't.
At Kona, we have not had a bad meal. Spotty service once, but that trip we were a group of 13.
Kona is a must for us every single trip. I love the food and my new favorite is the scallops and shrimp. I have the shrimp not fried but cooked like the scallops and it is fantastic.
For antics and fun servers we do WCC and PTC. Ohana is not on my list. I wish it would be, I used to love it, but I will not go back to a place that has disappointed us time after time.
Let us know what you decide and when you get back, let us know how it was.
