Tips (Tipping): Tipping is a fundamental part of the culture and income of many workers. In restaurants, it is expected to leave between 15% and 20% of the total bill before taxes. It is also customary to tip taxi drivers, hotel staff, and tour guides.

Transport: For long distances, the plane is the most practical option. To explore regions, renting a car is almost essential, as public transportation outside the big cities is limited. Major cities usually have efficient subway or bus systems.

Taxes (Sales Tax): Prices shown in stores and on menus typically do not include sales tax. This is added to the total at checkout and varies by state and city.

Travel Insurance: It is extremely important to purchase travel insurance with extensive medical coverage. Healthcare costs in the United States are very high and any emergency can result in an astronomical bill.
