I don't believe the decline in "market share" has ANYTHING to do with "hostility," whatever that means. It is simply a fact that the world is getting smaller, and it is cheaper and easier to travel to destinations that would once be truly expensive or difficult to reach. Many travelers seek the new, and so they seek out these newly open destinations. There's nothing you can do about that. We have to share the market with everybody else. The more tourist infrastructure there is throughout the world, the more people feel confident about traveling to a destination they might have once feared. Also, there's a "me too" mentality that probably dilutes market share for non unique destinations. Do you really need to go to California to visit Disneyland, if you can go to the one in Paris? Does anyone care that you went to Vegas like everybody else, or should you consider Macau? Not to mention all the little countries with no $ who figure they'll just make their fortune having all inclusive beach resorts. That kind of tourist doesn't care where they go as long as it's cheap. Should the USA compete with them on price? I don't think so!
