We have been to both and thoroughly enjoyed them both. The Whispering Canyon had fun games and the interaction with the servers is really fun. Like one would get up on a chair and say,"Can I have your attention for a moment......when it got quiet he said, " thank you." and got down. They announce to the whole room, " Tommy here isn't eating his vegetables!" It was very funny and festive. We loved the food, all you can eat ribs, cole slaw, BBQ beef, corn on the cob, baked beans and tons more. The Wilderness Lodge is a sight to see in itself. This one might be better for younger kids.
Now for Ohana. We totally loved this place and plan to go back on our next visit. The food was awesome(although we are easily pleased and not gormets) huge shrimp, huge chunks of beef, turkey and pork i think. The room was fun too with the grill in the middle and the huge skillets and skewers full of meat they bring to your table. We got a table by the lagoon and had a beautiful view. The say get a table an hour for fireworks to see them at MK. Be sure to wait for a table in the main dining room. They had roving minstrels playing guitar, but only only one game while we were in there. It was a hula hoop contest. My kids were 14, 11, 9 so only the youngest played anything. I think older kids would enjoy Ohana more.
You'll love either one.... or do both!!
