Atlantis, The Palm, is the flagship resort of Palm Jumeirah, one of the three palm-shaped artificial islands off the coast of Dubai.
Though it had opened its doors to guests and day visitors in September, it had scheduled its official opening for Nov 20.
Dubbed the first integrated entertainment resort in this metropolis on the Gulf coast, it is offering a whole range of entertainment and leisure activities themed around marine life apart from regular hotel facilities.
A creation of South African hotel magnate Sol Kerzner and Kerzner International, it is the second such resort in the world after the Atlantis Paradise Island in Nassau, Bahamas.
Set on the crest of the Palm Jumeirah, Atlantis, the Palm is one of the most luxurious resorts in the Middle East, with 360-degree views of the ocean, restaurants from acclaimed chefs, an 11 million-litre marine habitat called Ambassador Lagoon that is home to more than 65, 000 animals and a water park for leisure activities spread over 17 hectares.
Another attraction is the replica of the ruins of the legendary lost city of Atlantis, which Plato mentioned in his dialogues 'Timaeus' and 'Critias'.
The boulevards and ruins of the legendary lost city have been recreated on the seabed of the Ambassador Lagoon and visitors can view these from an underwater maze of tunnels called 'The Lost Chambers'.
Meanwhile, local authorities have imposed restrictions on the area surrounding the resort.
Residents of the Palm Jumeirah island will be granted access only on production of valid passes or sales or tenancy contracts.
Access to the resort itself will be blocked from Wednesday evening till Friday midday.
