Sorry for the delay getting back to your question.

Cruise lines with guests of different nationalities have got plenty of experience how to address their customers in various languages. It does not end with onboard entertainment.

Trivia games e.g. are conducted not only in English but often in a number of tongues. The conductor may speak four languages, for example, and an assistant even some more.

So the question "Who was the first man on the Moon?" would be asked in English, Spanish, Italian, French, and/or German, (depending on how many guests speak the languages) before the audience is given the chance to answer.
