I hope I can give you some insight into this, brotha. I was down there 2 summers ago, and stayed at the Atlantis resort. We booked the trip not too long in advance, so we didn't have a room with a view (the beach side hotel), but it didn't matter. We payed less, and didn't care 'cause we were never in the room to see the view! The casino itself is pretty big, and everything is within walking distance. True, the money gets veeeeeeeeeeery pricey, but you're on Paradise Island, and everything there can can be accessed by foot, as well. The resort has so many things to do, that if you stay for less than a week, you don't have to leave the hotel and won't ending up doing things twice.
Personally, I would recommend staying there for the experience. You'll end up staying up all night in the casino like I did, and the walk to the room (or lack thereof) makes the trip worth it. You'll be staying in luxury, so soak it up and spend the $$ if you have it! I think it's worth every red cent. There are so many things to do outside the casino that everyone can enjoy (from the shark-tank pool to the parasailing, to jet skis), I would definitely go back.
