Bahamas, staying at Cable Beach Nassau, but I can go visit the Atlantis aquarium?
without staying in the hotel Atlantis?
Yes You can buy a DIGS (aquarium) exceed $ 35 in the central kiosk Casino. This step does not allow access to the pools and slides .. just for the aquarium and pond pedators. Can not walk freely as others have suggested. There is no security in the whole procedure of control of ownership of the appropriate color bracelet. At Nite .. after dinner. you can go through security Excavations once you have vacated the area. Of course, it's too dark, and exhibits are not as interesting. Hey ____________________ P. Brain > The excavations and the lagoon all pedator, tubes and tunnels are not accessibe unless you have a bracelet of Atlantis. The only part you can see without having to pay is the small area in the Great Hall of Cafe waters. After 19:00 .. when security is going .. you can walk through the DIGS .. and outside the pool. NOT open to the public .. whether they are tourists, locals or rude. Security will stop entering the sites.
