This tour was really nice. It was an open bus and made 6 stops where they told us about the history of the island. Several of the stops you had time to shop and take pictures.
We didn't take an excursion on Nassau. We did get off the ship to do some shopping and I was not impressed. It was not clean and the people were pushy.
I am sure if you got outside of the port it would have been nicer. I heard some people went to Atlantis and really enjoyed it.
