In regard to CN: Actually, you can only make reservations at the Otaheiti...other restaurants do not take reservations. And you can only make reservations at the Otaheiti a few days in advance. You do this through guest relations at the resort (not in advance of arrival). Enjoy your stay!
We are going to CSS, and I am interested in the Cassanova. After reading all of the great replies it looks as if all Couples resorts must make you check into your room before being allowed to make dinner reservations. Does anyone have direct information about Cassanova at CSS?
