OurExplorer - Tour Guide language importance

As a tour guide did you ever wonder how much more business you could generate if you were fluent in another language.

Would you choose a language with a large global speaking population e.g. Spanish or Mandarin Chinese?
Would you be more specific so you may be the only tour guide in your country to speak a certain language e.g. Swedish?

The experience a traveller has with a tour guide is all to do with the relationship built via communication during the tour. So if you are going to invest the time on another language it may be best to only start if you are committed to a fluent level being achieved.

Did you ever benefit from learning a new language resulting in more bookings?
