Has anyone taken the Celebrity Beyond Destination Highlight: Panoramic Island Drive excursion in George Town, Grand Cayman? We booked the tour and its 4 hrs 30 min. The excursion includes a stop at the Seven Mile Beach for snacks, a drink, and photo taking at the beach. Wondering how much time you actually stay at the beach and if we should take our bathing suits. All of the beach excursions are sold out. Thanks!
