Atlantis, Paradise Island in the Bahamas rolled out a yearlong marketing campaign for the 3,141-room resort and casino.
The first 30-second TV spot debuted Jan. 4 on "Entertainment Tonight."
The "Only in Atlantis" campaign uses digital special effects in the television ads to follow a family as they explore the resort, meeting up with fish, dolphins and manta rays in the 140-acre marine habitat at Atlantis.
Campaign elements also include print ads and media websites.
In February, iPhone users will be able to download an application to explore the property, communicate with resort specialists, play games and stay in touch with resort events.
