Thank you for your message on my user page of Japanese wikitravel.

Well, the answer to your question is very much depending on what type of your stay you want the most in Mauritius. Do you want to choose quiet and isolated resort areas, or to stay more populated places with lots of play spots, restaurants, etc?

For your information, I listed some web pages which might be useful for you.
