Back in the olden days, when rich men sent their families off to the mountains for the summers, grand hotels were a big part of the New England scene. Few of these hotels remain. Many succumbed to fire, the rest to the end of the "privileged" class of society, and, to the invention of air conditioning!
Here in New Hampshire we had a number of grand hotels, most being situated in the White Mountains. To look back at the era of NH's grand hotels and their clientele and workers, you need to borrow White Mountain Hotels, Inns, and Taverns by David Emerson [974.2 EME]. It is part of the "Images of America" series that nicely integrates old photos, postcards, with brief descriptions to give you a real sense of hotel living.
A more complete history of some of the White Mountain hotels is found in And Then There Was One: A History of the Hotels of the Summit and the West Side of Mt. Washington by George E. McAvoy [974.2 MCA]. The "one" that remains is the Omni Mount Washington Resort in Bretton Woods. It is still going and is now owned by the Omni chain of hotels.
