MGM-Stay Well loungeThe 5,000-room MGM Grand Las Vegas has completed the expansion of “Stay Well,” a program that provides some guestrooms with special air and water supply as well as customized lighting,

The entire 14th floor of the hotel, 171 guestrooms and a new lounge, is now dedicated to the wellness program.

MGM converted 42 of the hotel’s rooms to Stay Well rooms in 2012, with the help of New York-based wellness architecture and design firm Delos.

The rooms include touches such as "wake-up light therapy" in which blue hues are used to better simulate natural daylight and reverse or minimize jetlag; vitamin C-infused shower water, said to neutralize the effects of chlorine and improve skin and hair health; air purification and water filtration systems; and a photo-catalytic coating on bathroom surfaces that breaks down bacteria.

MGM said Stay Well rooms and suites at MGM Grand are approximately $30 per night above rates for standard rooms and suites.
