Question

I am not sure if the number of travelling tourists might increase or decrease because of language differences.

Next, I have to explain why it would have this affect.

Answer 1

Many tourists, especially those who do not speak English, travel primarily to those countries that speak their language. For instance, many people from Spain visit Latin America.

Those people who speak English are more likely to travel to countries whose native language is not English. Why? Because many people who serve travelers speak English as a second or third language.
