9 nights from New York

The world famous city of New York , the largest city in the United States, with a population of 8.5 million people, and with suburbs - 20.6 million. New York is the largest economic, political, scientific, and cultural center of the United States. It is rightly called the "Main Gate" in the United States, and the world's largest John F. Kennedy Airport is located here. One of the distinguishing features of the city is the variegated national composition of the population, also called the United States in Miniature.

New York gathered in itself the whole essence of this country: fashion, religion, goods, pace and rhythm of American life. The UN headquarters is located here. There are also many universities in New York, the Academy of Sciences, and many other scientific institutions. Like any other metropolis in the world, New York invites you to visit numerous museums in the city, theaters and concert halls, including the Metropolitan Opera and Carnegie Hall. A great place to relax in New York is Central Park, where you can feed hand-held squirrels, which, to everyone's surprise, are not afraid of people. You can also appreciate the beauty of the famous Empire State Building, with a height of 102 floors, it is an example of skyscrapers, although it was built in 1829-1831. "Must see" in New York, of course, the Statue of Liberty ("Lady Liberty"), located at the mouth of the Hudson River, on the small island of Liberty. And of course, don't forget to stroll along Broadway.

Boston is the capital and most populous municipality of the Commonwealth of Massachusetts in the United States. The city proper covers 48 square miles (124 km2) with an estimated population of 685,094 in 2017, making it also the most populous city in New England. Boston is the seat of Suffolk County as well, although the county government was disbanded on July 1, 1999. The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston, a metropolitan statistical area (MSA) home to a census-estimated 4.8 million people in 2016 and ranking as the tenth-largest such area in the country. As a combined statistical area (CSA), this wider commuting region is home to some 8.2 million people, making it the sixth-largest in the United States.

Boston is one of the oldest cities in the United States, founded on the Shawmut Peninsula in 1630 by Puritansettlers from England. It was the scene of several key events of the American Revolution, such as the Boston Massacre, the Boston Tea Party, the Battle of Bunker Hill, and the Siege of Boston. Upon gaining U.S. independence from Great Britain, it continued to be an important port and manufacturing hub as well as a center for education and culture. The city has expanded beyond the original peninsula through land reclamation and municipal annexation. Its rich history attracts many tourists, with Faneuil Hall alone drawing more than 20 million visitors per year. Boston's many firsts include the United States' first public park (Boston Common, 1634), first public or state school (Boston Latin School, 1635) and first subway system (Tremont Street Subway, 1897).

The Boston area's many colleges and universities make it an international center of higher education, including law, medicine, engineering, and business, and the city is considered to be a world leader in innovationand entrepreneurship, with nearly 2,000 startups. Boston's economic base also includes finance, professional and business services, biotechnology, information technology, and government activities. Households in the city claim the highest average rate of philanthropy in the United States; businesses and institutions rank among the top in the country for environmental sustainability and investment. The city has one of the highest costs of living in the United States as it has undergone gentrification, though it remains high on world livability rankings.

Da Nang is the fifth largest city in Vietnam after Ho Chi Minh City, Hanoi, Haiphong and Can Tho in terms of urbanization and economy. Located on the coast of the South China Sea at the mouth of the Han River, it is one of Vietnam's most important port cities. As one of the country's five direct-controlled municipalities, it is under the direct administration of the central government.

Da Nang is the commercial and educational centre of Central Vietnam, as well as being the largest city in the region. In addition to its well-sheltered, easily accessible port, Da Nang's location on the path of National Route 1A and the North–South Railway makes it a hub for transportation. It is located within 100 km (62 mi) of several UNESCO World Heritage Sites, including the Imperial City of Hue, the Old Town of Hoi An, and the My Son ruins. The city was previously known as Cửa Hàn during early Đại Việt settlement, and as Tourane (or Turon) during French colonial rule. Before 1997, the city was part of Quang Nam-Da Nang Province.

On 1 January 1997, Da Nang was separated from Quảng Nam Province to become one of four independent (centrally controlled) municipalities in Vietnam. Da Nang is listed as a first class city, and has a higher urbanization ratio than any of Vietnam's other provinces or centrally governed cities.
