When they called these the "Top 10", they meant "Most Visited", which are not necessarily "The Best 10". Measuring the popularity of a place by the number of visitors is a lot easier than by other more subjective qualities. Still, I was surprised that other highly touristy spots did not make the list, such as the "Walk of Fame" and Grauman's Chinese Theater in Hollywood. Does that really have less traffic than the Navy Pier in Chicago? I am really curious about how they count the traffic. Perhaps some of these places have a lot of local traffic.
Anyway, despite what some may say about Faneuil Hall and Fisherman's Wharf, they are popular and will continue to be frequented by first-time visitors to Boston and San Francisco. Come on! Wouldn't you go there just to see for yourself how "disgustingly touristy" these places are? Oh, I forgot that most of us have been there already, in order to sneer at the tourists still flocking there.
Don't be too harsh! I am not ashamed to say we enjoyed walking the area around Faneuil Marketplace looking for a place to eat. Yes, it is touristy, but no more so than Boqueria Market and La Rambla street in Barcelona, or the area in Amsterdam around the Royal Palace, or the Montmartre in Paris, or the entire inner city of Prague. Come to think of it, most of the places we have visited have been touristy; we did find these places in some guidebooks after all.
Places like the Disney parks, unless we have grandchildren to entertain, I do not see ourselves visiting again. That goes for any amusement park, and even top zoos like the San Diego Zoo (we have been there 3 times). Once one has been to these "top" places, then it is time to venture out to lesser known places. And in an RV.
It is too early yet for me to start thinking of an RV in Europe, but I still have some time left, I think.
