The Grand Canyon National Park not only hosts plenty of American guests — people come from around the world to see this geological marvel. While there are plenty of camping — and even "glamping" options, if you want to stay in style, you can’t beat the El Tovar hotel, which sits right on the South Rim of the canyon in northwest Arizona. (It's the dark-brown structure in this photo.) Run by the National Parks Service, the El Tovar, which opened in 1905, is the most dramatic and luxe of the lodgings in the Grand Canyon, and has hosted luminaries from Albert Einstein to Theodore Roosevelt and author Zane Grey. Three view-suites are available, but those book up often a year in advance; standard rooms are less than $200 per night and you still get the chance to revel in the views — and history — of this famous location.
