Beautiful island w/ alot of history and very nice people. We didn't do a Carnival excursion here, and glad we didn't. As you come off the dock you will be greeted by several bus/taxi drivers who will offer to take you on a 2 hour history tour of the island... we did this... and was great. I paid (w/ tip) $75 for my wife, daughter, and me... and we were taken to every major part of the island, and even thru the lower class neighborhoods where the Haitian immigrants primarily lived. Very educational as Nassau is the capital of the Bahamas. The driver was an incredible wealth of knowledge and very good. You get to stop and shop at the Queen Charlotte's staircase... and get out at the Atlantis to do a 15 minute walk around. After that the drive took us to Cabbott Beach by the Atlantis where we spend the rest of the afternoon at a gorgeous beach... just $4 a per each to get back to the port. I would highly recommend doing this if you want to get a good view of the island, get some history, and then have some fun at the beach too.
On the Atlantis advise... on the ship, its $175 per person for the day at the Atlantis, doing the slides and everything else. The driver told us that the Comfort Suites, right beside the Atlantis, had an agreement where if you book a room at the Comfort Suites, you get one free Atlantis pass for a day for 4 people. The rooms at the Comfort Suites go for about $250 / night. So, book the room on the Internet in advance (this is a requirement)... pay $4 per person to get from the port to the Comfort Suites... check in and enjoy your day at Atlantis... then pay $4 per person to get back to the port. You just saved $400 for family of 4. Wish i had known!!!!
