The Nassau airport is about 45 minutes from Atlantis. During your ride to the resort, you'll pass the cruise port, which is about 10 minutes away from the resort. There's also a water taxi that you can take from the cruise port. If you book an excursion with your cruise line, transportation will most likely be included. If you are flying in and out of the Nassau airport, you'll want to arrive early for your return to the United States. You'll be going through US customs right in the Bahamas. That takes a little extra time in Nassau, but then you'll skip customs in the United States.
