Margaritaville's is not very child friendly nor is the food worth the $.It is often too crowded & noisy.After eating quite a few "cheeseburgers in paradise" in Key West's Margaritavillle City Walk's is pretty weak anyway.But everyone should go once just to do it and be done.
Leaving the park to eat and returning is lot of walking for kids.We leave only if to go back to an onsite hotel for a nap if the kids need one.The resort resturants are very good as well.
