Access Atlantis, but save some bucks on lodging?

Hi! We once spent a day at Atlantis as a part of a shore excursion from a cruise. We really liked it and would now like to do a Bahamas trip. Atlantis is pretty pricey, though we aren’t cheap, we aren’t made of money either. I have heard that there are other hotels that are affiliated with Atlantis, are nice, but not so expensive. Do you know of any and can you suggest where I could look for more information. Thanks!
