We did the Historic Harbor and Discover Atlantis shore excursion. My husband and I had stayed at the Atlantis Resort for our 20th anninversary in 2000 and we wanted the rest of our family to see the resort. It was a great tour. However, be prepared for a lot ot walking once you get to the resort. Because of a lot of construction occurring, we had to walk around it in order to get to the beginning of our tour. It was also quite warm. You may want to bring bottled water with you since there is no time to take a drink or potty break.
