It is FANTASTIC. The only thing that was not really great was their beach. Kinda steep drop-off, usually some fairly high surf... (No way that DS could get in the water....) And it is not all set up with beach chairs, no shade, etc... We found it a little un-inviting, and returned to the pools and other resort amenities. Had a great day!
Also, we rented at the Comfort Suites for our day at Atlantis. (It is a very short and simple walk across the street.) And, I believed that the room rate was for up to 4 persons. (I have heard of the high surcharge at the Atlantis.) There is a small mandatory Bahamian energy tax per person. Or some such fee as that. But I was not aware of any Extra Person surcharge at all.
We booked through the Comfort Suites online... But had pulled up Placestostay.com where promotional rates are listed that I have never seen elsewhere. We got our room for around $135.00 plus the taxes/fees. We just called the Comfort 800 number and asked for the LGOLD rate.
