The MGM Grand in Las Vegas expanded its meeting and convention space to 602,000 square feet with the addition of the Marquee Ballroom, a pillarless 92,000-square-foot structure.

The multi-purpose building is capable of accommodating 6,000 guests and can be used for trade shows, general sessions and catered functions of all types and sizes.

The standalone structure was constructed without the support of pillars, which makes the space more flexible. Earthy tones give the huge, fully carpeted space a comfortable feel.

The room has floor-based power, wireless Internet access and convenient rigging points throughout. The building replaces a temporary outdoor tent that was built and torn down as needed.

Also, a $110-million room and suite redesign has begun at the Mirage. From luxury amenities to modern furnishings, the 2,765 Deluxe and Tower Deluxe accommodations will reflect contemporary upscale living.

The design will feature neutral colors accented with vibrant colors, cool metals and warm woods. Each room will feature a pillow-top mattress, down comforter, feather pillows, 42-inch LCD TV, iPod/MP3-compatible clock radio, cordless phone and comfortable office chairs.

A cool marble foyer leads guests into the Mirage's Deluxe King room that includes a sleeping area featuring creamy white and warm brown colors.
