I don't think its particularly typical of any nation. I DO know exactly what you mean as well. Why travel half way across the world to eat what you eat at home, speak the language you speak at home, etc?
For me, and no doubt for many of the posters on here, part of the point of travelling is to sample the different cultures of other countries, if you don't do that, then what's the point?
Spanish resorts are a good example - Spain has a rich cultural heritage, but people aren't interested in that, they just want sunburn beer and sexually transmitted diseases....
The same goes for Amsterdam, people travel all that way, and don't bother trying to speak any Dutch (although I must admit my attempts have always been met with English responses), don't check out the marvellous Rijkmuseum, Van Gogh museum, etc, the cafe culture (I can't remember the places are called brunhuis or something similar?) or even explore the canals...they just want to pay for sex and get stoned... But then despite all my whingeing - its their choice, I just reckon their missing out!!!
