History buffs rejoice: these 10 historic American hotels offer a lot more than just a place to rest your head. Retrace the steps of storied guests at resorts counting Hollywood celebs, U.S. presidents, and international royalty on their lengthy rosters of legendary one-time lodgers. Or, opt to admire some of the richest architectural ambience and decadent design in the nation, with styles ranging from Art Deco to Mediterranean Revival (and many others in between). Choose from a quintet of history-steeped, sun-drenched gems in Florida and California; celebrated central-city quarters in Boston, Chicago, or N.Y.C.; a preserved piece of the Old South in New Orleans; or a legendary Grand Canyon lodge that helped to forever redefine “roughing it.” Happily, like an aged wine, these hotels of yesteryear have gotten only better with time, with careful preservation efforts ensuring that much of their rich history remains to be written.
