We stayed at the RYU recently (which is right beside Atlantis on Paradise Island). It's all exclusive and the food is not bad. I would highly recommend to upgrade to a suite instead of the regular rooms.
It's the best of both worlds as it's right beside Atlantis and you can go over and gamble and also not break your bank on the ridiculous prices on food and such over there as it's included at the RYU.
Just my 2 cents
