I was very interested in the tantilising questions raised by your brief study. I'd be interested to know how you would offer tentative answers yourselves. As a director of a travel company, I know how imperative it is that one's agents and partners in othe can be trusted.
Legal sanctions are hard to rely on in other countries.
It is far better if trust is built on the basis of long term personal relationships where trust is demonstrated and reciprocated. In such a market as tourism to the Holy Land, one can rely on a level of governmental interest in that it is in their interests to ensure agents, hotels and travel operators do not tarnish the image of tourism in the country. In our case we have worked with family based operators for decades who care more about their reputation than making a fast profit. Ultimately reputations are hard to earn and easy to lose in a competative market.
