Avid travelers want to see and experience everything a destination has to offer. Many tourists often start with the most popular attractions if they are in a city for the first time.

Never been to Paris? Your first trip is likely to include the Eiffel Tower. Going to London? You probably won’t skip Buckingham Palace. Flying to New York City? You may stop at Times Square before you even get to your hotel.

But not every popular or even iconic attraction is worth the time or money. Though personal opinions, taste, and preferences regarding vacation destinations and activities change from person to person, huge crowds are a buzzkill for almost everyone.

Too many people mean long lines and a lot of waiting, which can add hours to a simple sightseeing trip. The result is an overwhelming feeling of “we should have gone to this other place instead.”

Crowds, which usually lead to a commercialization of a place, taking away its authenticity, are not the only reason to stay away from some sites. Cost, unrealistic expectations, and lack of entertainment are other reasons to avoid some destinations.
