We will be in Grand Cayman Jan 18-25 and would like to do a Stingray City trip but since we have previously visited the sandbar we would like to go where the water is deeper and you can actually snorkel. I do not see very many tours that go to that site - any recommendations? During the dates we will be there, is it possible that it may be too choppy to snorkel? Would appreciate any comments - also wondering if we would need to make a reservation prior to our arrival - we would like to avoid cruise ship times? We have visited on 2 previous occasions (pre-hurricaine) so anxious to see if we notices any obvious changes.
