As someone who has lived overseas (Germany 4 years, Saudi Arabia 5 years) and traveled to 81 foreign countries, I was a bit put off by the negativity of this article.
First of all, I don't find that American travelers are shallow, arrogant or ignorant when they travel. Having visited 81 foreign countries on all the continents except Antartica, I generally find fellow American travelers to be good natured, flexible and friendly. Yes, there are rare cases of an " Ugly American."
Second, I moved overseas in 1981 when I was 33 years of age, having never been out of North America. Bach then, crowds were way smaller and the Americans you ran into overseas were of two general categories: 1) well to do people or 2) military or families of military stationed overseas. This is not the case today. Air fares are relative cheaper than they were over 45 years ago, but now more people have the money to travel. Also, more people travel quite a lot. This makes travel more of a hassle these days, since now if you want to see the Sistine Chapel or see the Coliseum/Forum in Rome, you must book in advance. Getting into the Anne Frank House in Amsterdam now requires booking the minute after such bookings are open. In 1982 when I first visited the AF House, no prior booking was required.
Third, the ariticle does make some good points. Yes, many people want to see the IMPORTANT places, like the Sistine Chapel and Colliesium/Forum. Can you blame them? Why go to Rome without seeing those sites, or Paris without going up the Eiffel Tower? Yes, having a bucket list is normal. I have accomplished about 90% of mine, as I am 75 years old. Still, there is a lot more to see.
Fourth, the method of travel is important. When younger with less money to spend and more energy, I usually planned trips where we did stuff on our own. We didn't do a lot of tours where you did Italy for 14 days on tour. We saved by staying in pensions, taking subways or walking and using guidebooks. Now, most of our travels are done on tours. Planning is not hard, most of it is done by the tour company.
Fifth, the place you visit makes a huge difference. When visiting third world countries or countries like Russia, China, India or the Middle East, it is wise to take a tour. It is easier to get a visa to visit Russian and China if you are on a tour. Also, safety is a huge factor, especially visiting places like Egypt, Jordan or a safari in Africa. I very much enjoyed going to Russia and China on a tour.
Sixth, we have enjoyed taking cruises, all over the World and usually try to combine a cruse with a land trip for a week or so. On cruises you meet a lot of people that are well traveled.
Travel is still loads of fun, not an unfun bloodsport as the article propounded. Get out there and see the wonderful World. I have enjoyed everywhere that I have been and still can't wait for my next trip.
