I am a graduate majoring in hotel management. What do you need to engage in the cruise industry?

Cruises are not the same as cruises. If it is a cruise ship, it is similar to a star hotel, but it is a luxurious swimming star hotel with restaurants, rooms, entertainment and other facilities. With hotel management experience and related skills, I may have some requirements for English, because most cruise ships have many foreign tourists. If it's a cruise, I'm not sure.
