Book excerpt: The criteria for designation as an American Historic Hotel is to be at least fifty-years-old. The first ten hotels are Historic and the next seventeen are notable for unique features. Arizona is a unique state with characteristics not found elsewhere in America or the world. There are beautiful natural wonders such as the Grand Canyon, early Western history is recreated at dude ranches, and there are even historic “treatment” facilities such as the Castle Hot Springs Resort. Historic hotels capture earlier times. This comprehensive guide describes rooms, rates, and amenities. It includes details of movie locations, famous guests, and notable recipes. This history of Arizona includes hotels famous for the “Five C’s of Arizona:” Cattle, Citrus, Climate, Copper, Cotton, and even an extra C for Convalescence since doctors prescribed a visit to Arizona as treatment for many ailments. Guests armed with this knowledge can better enjoy their visit to all parts of Arizona.
