The majority of the top 20 biggest hotels in the world can be found in Las Vegas. The Bellagio hotel, found right in the heart of 'The Strip', may not make this list but is still pretty vast in size, with 3,933 rooms, while the Wynn hotel nears 4,750 in number. In contrast, El Tovar in the Grand Canyon Village has a mere 78 bedrooms and has a little more charm and character, along with unbeatable views of the Canyon. However, it is possible to find (some) solace in the city itself, as the Mandarin Oriental is a casino-free haven away from the chaos, where you can escape to the spa rather than the gambling tables each evening.
