We ate at both on our last trip in March and I LOVED both!!! I thought the food was excellent at both (although I am not picky) and the entertainment was great fun. We have a 5 year old son, and also at the time (he's now 2) a 20 month old...the 5 year old thought Whispering Canyon was GREAT! They have a large table of lincoln logs to play with while you wait for your table, or your daughter could also play with them while you are waiting for your food, and the stick pony races were a hoot! All the kids get a certificate for participating in the race and have to "promise" to eat their veggies, mind their parents and NOT go to SeaWorld.
3 of the adults in our party had the skillet, which, as described before, had several meats, corn, stew, beans, and potatoes. The biscuits, salad and cornbread were awesome. My Mom had the pork chops and she thought they were great as well. My kids had hot dogs and they were standard fare. They also shared the bread.
'Ohana was great too--I don't think my son thought it was as much fun, but we had a SPECTACULAR view of the castle and the fireworks going off. It was magical. Everyone in our party of 5 adults thought the food was marvelous. Great wontons, salad, chicken wings, and my dad and DH thought the shrimp was soo yummy. I liked the turkey and beef. My 20 month old must have had 10 pieces of pineapple at the end. My kids were picky about the food, so the server immediately rustled up some hot dogs. Oh they also serve this delish Hawaiian sweet bread before they bring out the appetizers- very good. My son participated in the hula hooping, but didn't really "Get" it and the also have a coconut race where they circle the restaurant with a little broom and a coconut...my son lost his coconut underneath someone's table and was crushed. I told him he could still go get some gummi worms so that made up for it (they give out gummi worms at the end).
Anyway, in my opinion, whichever you choose, you will have fun! And you will eat well! I think for me it would come down to whether I wanted BBQ or home cookin versus marinated grilled meats. Go to
