The main cost of traveling to Philadelphia is transportation and accommodation. The cost of air tickets varies according to the time you buy it. Air tickets can range from a few thousand to more than 20,000; accommodation is up to you. For what standard you need, it usually costs about 140 knives to stay a night. In the United States, most restaurants where you sit down and formally order a meal are expected to tip about 15% (unless it is fast food, a buffet, or the bill states that Gratuity is included, no tip is required). There is no need to tip for fast food (such as McDonald's, street food restaurants, etc.), but you have to clean the tableware yourself. Sometimes for large tables with more than 4 people, the tip will be automatically added to the bill in advance, so be careful to read the bill clearly to avoid paying double tips due to misunderstanding.

Delta-Travel recommends a Philadelphia tour route: Depart from the hotel in the morning and drive to Philadelphia to visit Independence National Historical Park. Walking along the cobblestone streets, the silent Liberty Bell stands in the center of the newly renovated Liberty Bell. Walk through the ancient Independence Hall and pay homage to the Congress Hall. Then visit the University of Pennsylvania, then go to Chinatown to taste authentic Chinese food, browse the antique street, and stroll the elegant Benjamin Franklin Avenue. After visiting the Philadelphia Museum of Art, go to the lively Penn's Pier to enjoy the sea breeze and eat delicious food.
