We returned for the Western Magic 1 week ago and went to 7 mile beach. When you get off the tender in Grand Cayman, there was a man there holding a sign for anyone who wanted to go to 7 mile beach. There were enough people who wanted to go to fill his small bus. He charged $3.00 per person. Then he stopped at several resorts, explaining each one, and we could get off the bus at any. We got off at the first one. It was $3.00 per person to use the resorts beach, and they had tables and chairs, a bar and resteraunt. It was very nice. Then when we were ready to go back to the dock, there were buses always available, for $3.00 per person. It worked out quite well for us. There was even hair braiding at the beach, which kept DD occupied since she won't get in the ocean!
Have a great time!
