I'd go for WCC with children. We ate at both when we visited in October/November last year. Ohanas was lovely, both children HATED the starters (and neither are particularly picky eaters). The salad was ok for them and the chicken wings but they disliked the rest. They both liked the meat and potatoes (which have now gone) but didn't like the bread and butter pudding!!! The two adults in our party really enjoyed it all but admittedly the choice is limited.
At WCC we all chose our different starters, for main course we all had the skillet (chicken, ribs, beans, corn etc) which the kids loved and for dessert the adults had lots of choice but we were too full!!! The children had worms in dirt but could have chosen other items too.
We really liked Ohanas though and we're going to try breakfast there instead of dinner this time.
