Keep 'Ohana. Dump WCC.
Both are loud, but the food is much better at 'Ohana. We have eaten at 'Ohana twice and WCC three times. The last WCC experience left a lot to be desired due to mediocre food, slow service, and the noises which really bugged my son.
We ate at 'Ohana last week and loved it. Food is very, very good, and the whole thing is just classic Disney.
