I do not know if I want to go to the beach or Atlantis.
You can do them both for way less money. You can see "some" of the aquarium at Atlantis for free, or take one of "Discover Atlantis" tours they offer at the hotel.
is a link.
Cabbage Beach is beside the hotel, and is a free beach to enjoy. Take a Land
taxi over to hotel, not
taxi. The Straw Market is easily within walking distance of the cruise ship pier for some shopping.
