Hello CPSTX, welcome to Cruise-Chat! I never booked an excursion to the Atlantis Resort, but I have taken a cab there for about $4 per person. My wife and I walked around the hotel enjoying all the sites (including the amazing aquarium), and it was free. Then we walked just a few hundred feet from the resort and enjoyed a great time at Cabbage Beach, which is also free. Just some food for thought in case you wanted to spend all that money on something else.
