From our perspective, stay away from Pearl Island. The snorkeling was terrible, the stingray adventure was a joke, they had 9 or 10 stinrays penned up in a 50 x 150 area of the beach, it was more like a petting zoo. The staff was friendly, but it was not worth the time or money IMHO.
Others that spent the day at Atlantis were very happy with their day.
When you get off the ship you have all kinds of offers of taxi's taking you over to the Atlantis. One tour offered us the trip over and a tour of the Atlantis for $20.00 per person. Not bad! We didn't go...but wish we would have!
We were abit overwhelmed by all the people wanting to sell this or that when we got off the ship.We took the water taxi to Paradise Island(the taxi host was very entertaining).......walked around,went for a drink in the casino,went to the beach,walked around downtown Nassau,Hard Rock Cafe,Straw Market, Senor Frogs........so much to do .........so little time! You will have a blast!!!
