I've talked to several people who have said that the Scopalomine patches made them feel woozy and tired - made them sicker than they thought! You might try non-drowsy Bonine or the wristbands with the pressure points. They might work better for you. Cozumel - try Chankanaab. Great beach and snorkelling, short taxi ride, restaurant, bar/s and restrooms. Very nice place. Cayman - Sting Ray City for sure! Or, if you just want a day at the beach, try the public beach across from the Holiday Inn on 7-mile Beach. Have a great time!
