Queens is the most ethnically diverse area of its size on Earth, which means there's a little something for everyone. Chow down on Indian food, sit in on a traditional Irish pub music session, and dance the night away at a Puerto Rican nightclub, all of it located within a few subway stops. Queens is also the home of the Mets and the US Tennis Open, and the former home of the New York World's Fair, now Flushing Meadow-Corona Park, and Paramount Pictures, now the Museum of the Moving Image.

Famous as the home of Yankee Stadium, elevated trains, and dense apartment blocks, the Bronx is also the greenest of New York City's boroughs. Visit the gorillas at the famous Bronx Zoo or wander through the 50-acre forest at the New York Botanical Garden. Pick up some gourmet foods on Arthur Avenue, the Bronx's Little Italy, and have a picnic at Van Cortlandt Park, which features two square miles of boating, horseback riding, tennis, and the oldest public golf course in the United States.

One of the most historic cities in America, Philadelphia is an ideal place to spend a weekend - preferably a long one. Be sure to see the Liberty Bell and Independence Hall, where the Constitution and Declaration of Independence were signed. Both are part of Independence National Historic Park. Philadelphia also boasts some outstanding art museums, including the Rodin Museum. The Franklin Institute Science Museum is one of many area attractions honoring the life and work of Benjamin Franklin, the city's most famous ambassador. After digesting all of that history, be sure you save room for a classic Philly cheese steak sandwich.

Ketchikan, one of Alaska's most Southeastern cities, is the first stop for many cruises on their way to more Northern climes. A stay in Ketchikan itself can be rewarding, however, as the city is the gateway to Misty Fjords National Monument, an area so beautiful, it is known as "The Yosemite of the North." With steep valleys formed by glaciers and lava flows left by volcanic activity, Misty Fjords offers gorgeous views of natural formations, all reflected in the calm waters of Pacific inlets.
