When you're one of the biggest hotels in the world, a full renovation is a large undertaking. At the MGM Grand in Las Vegas, some newly remodeled rooms are now available for guests, but it will take a while until all 4,000+ rooms and suites are complete. After the end of 2012, the renovations will be complete, giving a face-lift to all standard guest room and suites. Until then, you'll have to ask about getting a freshly redone room when you book.

The rooms aren't the only thing being renovated at the MGM Grand. The entire property is getting a new look. The popular Lion Habitat is closing on January 31, and plans for what will go in its place have yet to be announced. MGM's Studio 54 nightclub is set to be replaced in 2012 with Hakkasan Las Vegas, a Cantonese themed restaurant and nightclub. (Studio 54 is currently set to close on February 5. The club has been open 14 years.) Brad Garrett's Comedy Club, formerly at the Tropicana, is moving to the MGM and is set to open in March 2012.
