I got married and went there for free....oh wait, you are talking about the town in Grand Caymans huh?<G> You will find a number of tours that will take you there and around the island for probably about the same price as a taxi just toi there.

Last year, I think we paid $30 (including tip) between four of us and our taxi dropped us off the the turtle farm, then to HELL and returned us to the ship.
We negotiated a $15/per person taxi tour of the island, spent as much time at each place as we wanted, including Hell. It was a great way to see the little island.
