I haven't been to CG. However like PP we did Narcoossee's and hands down the favorite meal and meal experience of the trip. We opened with Narcoossee's and closing with it could also be just fabulous. Besides you can have that YOAMD cheesecake. My mother almost fainted on site of it as well on taste!
Definitely book so you get to see both EWP and Wishes its very special and a great way to wrap up the trip.
