I am so sorry to hear that. Grand Caymen is a favorite port for us, but there is not much to do if you are there during weather like that. I have never been there when we couldn't tender directly into town... I would have jsut gone to Margarita-ville and hung out... But if you had to pay to get into town you are correct in saying staying on the ship would have been better...
