LAS VEGAS, April 25, 2013

LAS VEGAS, April 25, 2013 /PRNewswire/ -- MGM Resorts International (NYSE:
MGM) properties have been awarded a new designation by TripAdvisor^®, ^ the
world's largest travel website, that helps identify the most environmentally
friendly hotels.

Twelve MGM Resorts properties on the Las Vegas Strip were accepted into the
new TripAdvisor GreenLeaders™ program. The program considers a property's
holistic approach to "green" practices and ranks them based on four levels of
participation - Bronze, Silver, Gold or Platinum.

ARIA Resort & Casino and Vdara Hotel & Spa each received a Platinum
designation – denoting the highest level of environmental responsibility - an
achievement earned by less than 10 percent of participants. Gold designations
went to MGM Grand Las Vegas, The Mirage, New York-New York, The Signature at
MGM Grand, Bellagio, Monte Carlo and Mandalay Bay. Excalibur and Luxor
received Silver designations. Circus Circus Las Vegas earned Bronze. 

"The new TripAdvisor ranking system is a powerful tool for consumers to refer
to when they are selecting a hotel," said MGM Resorts Chief Sustainability
Officer Cindy Ortega. "We know very well that our guests vote with their
feet, and, increasingly, guests are placing environmental responsibility high
on their priority lists when making important travel decisions."

TripAdvisor lauded MGM Resorts for its sustainability practices and

"MGM Resorts has an impressive number of properties that are dedicated to
educating their guests and potential guests about the sustainability aspects
of Las Vegas," said Jenny Rushmore, director of responsible travel for
TripAdvisor. "It is clear that MGM Resorts has demonstrated that the company
is truly committed to reducing their resorts' environmental impacts and
increasing the transparency of its 'green' programs with guests."

TripAdvisor has launched the GreenLeaders program with more than 1,000
properties, comprised of independent hotels to multinational brands. Web
surfers can refine their search on to hotels that hold the
"green" designation, and a view of each hotel's sustainability features.

Prior to launch, a comprehensive range of sustainability aspects at each hotel
were analyzed, from linen re-use, recycling, car charging stations, green
building materials and more.

TripAdvisor developed the program in partnership with the U.S. Environmental
Protection Agency's ENERGY STAR^® Program, the U.S. Green Building Council,
and the United Nations Environment Programme.

Recent statistics revealed by TripAdvisor surveys show that 79 percent of
travelers place importance on destinations that implement eco-friendly
practices, and 86 percent of hoteliers in the United States state that they
have green practices in place.

In 2009, CityCenter was awarded six LEED Gold certifications for sustainable
design and construction from the U.S. Green Building Council. In 2012, MGM
Resorts was awarded 15 Green Key Hotel rankings for designation of green
business operations. Also, in 2012, Green Key Global's Meetings Program
awarded the "5 Green Keys" rating to the meetings and convention spaces within
Bellagio, ARIA, Mandalay Bay and MGM Grand Las Vegas. For three consecutive
years, MGM Resorts has been listed as the highest ranking company in the
casino-resort industry among Newsweek Magazine's 500 most environmentally
responsible companies.
