The company said Vdara will open on Oct. 1 and will be followed by Mandarin Oriental, the Crystals retail and entertainment district in early December and the ARIA Resort and Casino on Dec. 16.
In making the Monday announcement, the company said it expects CityCenter "will become the cultural centerpiece of Las Vegas."
"The launch of reservations for Vdara and ARIA brings us one step closer to the opening of this magnificent urban resort destination, which will introduce a new generation of Las Vegas experiences and become the benchmark for hospitality across the globe," said Bill McBeath, president and COO of ARIA Resort & Casino.
Nightly rates for the all-suite Vdara range from $159 to $2,000 and for the ARIA, $179 to $799. Suites in the ARIA will range from $500 to $7,500 per night.
