Sidenote For the purposes of this site only, the term "travel agent" will define the person who can book your holidays under commission in your country.  As opposed to a tour operator, who will sell you a "package holiday" and will charge you per head -including the yacht or hotel, the flights and all other sort of expenses-, a travel agent will charge you per yacht/week and the flights separately.
