We are wondering about the retail store hours and the shopping availability at Grand cayman and Cozumel. We were planning on an afternoon excursion in Cozumel, and we don't get there until 10:30, so will there be any time for shopping? And are there any deals there? And essentially would like to know the same thing about Grand Caymen - when do shops open? And, what types of shops do they have, and close to the ship is the shopping? I will appreciate your responses!
