Mignon, part of the problem is that there isn’t one stereotype (for Americans or for people from any place). So don’t even try that as a basis. Maybe in 1970 when most US tourists in Europe came from similar backgrounds, but travel is a lot more open now.
I think you are of better service sounding militant than those pretending to be an expert on a place they spent one day in 3 years ago. I get a few comments about my militance so I put this on my profile: “BUDAPEST: I post a lot on Hungary, not because it’s the end all destination, but because I enjoy it and it’s a place about which my responses will be the most accurate and hopefully useful.”
The other thing that I think is useful is making out of the box suggestions. A person says they are going to Croatia for the beaches, I suggest Albania while they ae at it. Maybe one in 50 will look up Albania and maybe one in 10 of those will be adventurous enough to try it. Those few that did, would be happy they did, so I did a good thing.
Another difference is knowledge, opportunity and investment. The questions may be coming from a person who just invested 4 months of their income into a trip that is a once in a lifetime experience in a part of the world they know nothing about where they will have their first and only life time experience riding a train and have to deal with people who don’t speak the same language for the first time in their life. That can be hard for a person that grew up in Europe to wrap their heads around.
