I agree with
@epcotisbest. If the picky eaters won't eat any one or more of stir-fried veggies, lo mein, tossed salad, sticky chicken wings, grilled shrimp/steak/pork and/or dessert, there's no point in taking them to 'Ohana. You'll be paying "all-you-care-to-enjoy-themed-meal-with-entertainment" prices ($50 per person ages 10 and up, plus tax and tip) for them to eat the same chicken nuggets and fries they could get for a fraction of the price at any counter-service location. If it was just one toddler who didn't care for the 'Ohana menu, I'd say go for it, but since you're talking about two full-priced "adults", I'd either: (1) keep the reservation only for you and the non-picky eater (the rest can go to Captain Cook's and nugget it up); or (2) skip it altogether -- and perhaps consider Kona Cafe, where you can order a la carte and everybody can find (or customize) something to their liking, whether it's a stir fry, sushi, or a hamburger.
