I want to take my daughter who graduated from junior high school to travel to the United States in the summer vacation.

It depends on how many days your trip is, whether you want to go to all the key cities in the United States, or whether you want to focus on the west coast or the east coast first. Moreover, the purpose of the trip is to show children the cities and scenic spots, or to let them visit famous schools such as Harvard and Yale. If it takes a short time to visit scenic spots by plane, you can first concentrate on the west coast, such as San Francisco, Los Angeles and San Diego in California and Seattle in Washington, and you can also visit the University of California system, the University of Southern California and the University of Washington.

If it's on the east coast, it's new york and Philadelphia, and then visit world famous schools, such as Harvard, Yale, Massachusetts and University of Pennsylvania, which are all concentrated on the east coast.
