Tours in nassau

Does anyone know of a reliable tour operator to see highlights in Nassau? We would like to see Atlantis and maybe more!

We booked a cab ahead of time and paid $45 per person and then was added another $10 PER person when we decided to eat. We assumed (wrongly) that our cabbie would stay with us throughout the tour. We were dropped off at 3 locations and left for over an hour at each and had to wait and wait for our cabbie to return for us. You are better off just taking a cab where you want to go and then getting a cab when you want to be picked up and taken to another location. We were very disappointed and didn't appreciate sitting and waiting.

Would never do another Nassau "tour".
