ARIA, the main hotel component at City Center, is taking reservations starting today. The first night for regular guests is December 17.
The Web site for bookings, which also contains some new renderings of the property and rooms is here:
Rates for opening night are currently at $299 (ouch) for what is normally a very very slow week in town. We'll see if those come down.
Reservations for Vdara, the condo hotel next to ARIA, are expected to open today as well [online here - thanks Mike P!] for dates starting in October. Not sure what it will be like to stay in what will still be a construction site in the delta between those two openings.
This is the first opening of a [ed: Las Vegas] hotel for MGM Mirage since the company was combined in 2000.
