How much does this cost, and are there any potential discounts early in the year? Some friends and I are actually interested in going, but still young alum..
Atlantis isn't cheap
Atlantis is very expensive, but there are much cheaper options on Paradise Island within walking distance and a lot more in nearby Nassau.
Classof2013, if you can get a group of 3-5 people and can spare the time, the cheapest option would be to drive to Ft. Lauderdale and take a round trip two-night cruise ship. They leave at 5 PM from Ft. Lauderdale every other day, dock in the Bahamas at 8AM, and usually leave around 6 PM the next day but you can schedule a return on other ships if there is room. I've done this before without a problem to stay a few more days. It's not a fancy ship, but it's a legit cruise with food included, a casino, bars, cabins, etc. Just be careful what island it goes to as most go to Freeport and that is 100 miles from Nassau.
It would cost each person in a group of four about 150-200 for cruise, 50-60 for share of gas and tolls, and 25 or so a night at a place like the Paradise Island Comfort Inn if you shared a room. All of that for what it would cost for a plane ticket from NYC or less. Game tickets, booze, and non-cruise food would be extra. You could all work Monday that week if you left by 7 PM and took turns driving through the night.
