You might never have heard of DiamondRock Hospitality, but if you regularly stay at upscale or luxury hotels in top travel destinations in the United States, you likely have stayed at one of its properties.

And it’s one of the hotel industry’s 21st century success stories. Starting from scratch in 2004, DiamondRock now owns 36 premium hotels with 9,746 rooms, holdings that have pushed its stock market value to $2 billion.
