Hi! We're going to stop at Grand Cayman and want to go to Sting Ray City sandbar. There's a few non-swimmers in our group so they want the boat as close as possible to the sandbars and I've been reading that it depends on the boat and tour company. We're currently deciding between Moby Dick's or Island Marketing (Hannibals). Does anyone have experience with either of these or others that get close enough? Thanks!
