Last-minute Labor Day deals for hotels on the East Coast

Although time travel has not been invented, we here at Oyster can still take you back to the days when Paul Revere trotted along on his horse and George Washington planted big, sloppy, wooden kisses on Martha. Last week, we gave you a look inside the past lives of three of our favorite historic hotels. After the jump, check out four more hotels that have been around to witness momentous events in our nation's past and played host to political figures, celebrities, and world-famous athletes. Luckily for you, these hotels are all on sale for Labor Day, so you can experience a bit of history and save a little cash.

Boston

Copley Square Hotel

Sale Price: $239/night (you save 25%)
List Price: $319/night
Rating: 3.5 Pearls
Location: Back Bay, Boston

The landmarked Copley Square Hotel, opened in 1891, is the second-oldest operating hotel in the country. It has hosted everyone from Babe Ruth to President McKinley, and Billy Holiday sang at the hotel's now defunct famous jazz club, Storyville. The $18 million renovation in 2008 unfortunately didn't honor the property's past, but history buffs can head to the Freedom Trail, a 2.5-mile red-brick path to 16 historically significant sites, which begins only a few blocks away.

Back Bay Hotel

Sale Price: $281/night (you save 15%)
List Price: $331/night
Rating: 4 Pearls
Location: Back Bay, Boston

It's hard to imagine that the homey, 225-room Back Bay Hotel, with its cozy, comfortable rooms was ever an office building where the work centered around gritty crimes and hardened criminals -- but that's exactly what it was. Built in the 1920s, the hotel building was Boston's police headquarters throughout the last century. The cheeky name of the bar, Cuffs, and the lobby's black-and-white photographs from its days as police headquarters pay homage to the property's past. Engraved letters on the building's stone exterior still read: "City of Boston Police Department Headquarters."

New York City

The Plaza

Sale Price: $845/night (you save 20%)
List Price: $1056/night
Rating: 5 Pearls
Location: Midtown East, New York City

It could be said that no other New York hotel is as synonymous with luxury as the century-old Plaza, or has carved out such a place in 20th-century culture. Truman Capote threw his famous Black and White Ball here; inNorth by Northwest, Cary Grant was captured by spies in the hotel's famous Oak Bar; F. Scott Fitzgerald staged part of The Great Gatsby here; on their first visit to the States, The Beatles took up an entire wing on the 15th floor. And last but not least, Crocodile Dundee pitched a tent on those 400-thread-count bed sheets.

Washington D.C.

The St. Regis Washington, D.C.

Sale Price: $285/night (you save 10%)
List Price: $316/night
Rating: 4.5 Pearls
Location: Downtown, Washington D.C.

President Calvin Coolidge cut the hotel's ceremonial grand-opening ribbon eight decades ago, and since then, the hotel has been visited by every U.S. president (Reagan had his hair cut there) and numerous celebrities (Audrey Hepburn, Elizabeth Taylor, and Cher) were frequent guests. Howard Hughes kept a permanent suite at the hotel during World War II. In 1999, the hotel -- formerly known as the Carlton Hotel -- changed hands and became the second St. Regis in the world.
