There is a work around for those wanting to visit Atlantis in the Bahamas but not pay that high Atlantis price. Stay at the Comfort Suite Paradise Island instead.
The Comfort Suites is located across the street from the Atlantis complex. A family of four is $136 in two double beds. Less than half of the cheapest Atlantis room a night. (Or 25,000 Choice Points a night instead of cash.)
You will need to visit the Atlantis Royal Tower for your Atlantis wristbands after you check in at Comfort Suites. Along with full access to Atlantis, you also get a card from Comfort Suites that allows you to charge food and beverages at Atlantis to your room at Comfort Suites.
Breakfast is included at the Comfort Suites, the usual eggs, bacon, waffles and cereal. Basic but free. The rooms come with a refrigerator so you have the option to purchase water nearby and keep it in your room. If you wish to be closer to Atlantis please request the 2nd floor near the Atlantis exit.
If you are on a cruise you can also book a room for 1 day, this will get you Atlantis access much cheaper than the cruise ship excursions. Just taxi over to the Comfort Suites to check in with them and then head to Atlantis.
