If you're looking for great beaches, Nassau is a great port to visit while on your cruise.  If on the other hand you are looking for a nice relaxing break, you will find that here as well.  It's a great place to meet people, as there are so many people who travel here for vacations, and there are a lot of activities to do while here. 

The capital city of the Bahamas is Nassau.  It is normally paired with Paradise Island since they are so close and you can drive over a bridge from one to the other.  They both have many things to do, and will make your vacation a fun one.

Because of the islands' location in the Caribbean, snorkeling and scuba diving here are great, and you will see a lot of reefs, tropical fish, and even some historical wrecks.  If you're interested in botanical gardens, you can visit either the Ardasra Gardens & Conservation Center, or "The Retreat". 

There are many hotels to stay on at these two islands, with the most popular being Atlantis.  They have a casino, a lot of pools and other water rides, and sports.  They have gorgeous aquariums, an interesting tour, and many great restaurants.  Even though you won't be staying here, it is worth stopping by as it is a beautiful resort with a lot to see.  Depending on your cruise line, you will most likely be able to take an excursion here, where you will be able to spend the day at Atlantis.

There is also a lot of shopping nearby, so you can easily walk up and down some of the streets looking at the nice shops.  There are a few casinos on Nassau/Paradise Island.  One is at the Atlantis Resort, and another is at the Wyndham, called the Crystal Palace Casino.  There are also plenty of restaurants and bars to visit.

If you are looking for some different things to do on Nassau, you can visit the Bacardi Distillery, Fort Charlotte, or go on a walking tour of Nassau.

As you can see, Nassau will please everyone.  While you can take a tour with your cruise ship, everything is close enough that you can easily just walk around Nassau on your own, or take a taxi to get to anything you want to visit.  You will definitely have a great day at shore while you are at Nassau.
