Answer:

I recomment looking at the websites in sources

The following is from the first source:

Although few college courses relate directly to travel or tourism, a college education sometimes is desired by employers to establish a background in fields such as computer science, geography, communication, foreign languages, and world history. Courses in accounting and business management also are important, especially for those who expect to manage or start their own travel agencies.
