Atlantis Resorts debuts its first U.S. property at Ko Olina, on the west coast of Oahu, Hawai’i. The resort will be built on 15 acres of vacant oceanfront land on the Diamond Head side of Disney’s Aulani Resort.

The resort will be similar to Atlantis Dubai, with many planned amenities including Dolphin Bay, an interactive aquarium and a shark habitat, among others. The 5-star resort will have more than 20 restaurants, a nightclub, spas, salons and a fitness center. The resort will be a combination of hotel, condo and timeshare units.

The property could be the most expensive resort ever built with a price tag of more than $2 billion.

The Atlantis Resort is planned to attract millennials from all over the world. It will be designed as an “international destination for millennial travelers.” The resort will include hotel rooms with views looking into a giant aquarium. “This aquarium will look as the ocean looks. It’ll look as the sea looks today. You’ll be able to view it underneath. You’ll be able to interact with it, actually swim through it, and you’ll be able to learn from it in a natural setting,” said developer Jeff Stone more than a decade ago when the project was speculation.
