Traveling in Europe

 Generally speaking Europe is more densely populated than the U.S. However, the East coast in some ways population density wise sometimes compares to Europe. Generally countries are more ecological than the U.S. tends to be. Hotel Accommodations are generally somewhat more expensive than the U.S. for comparable accommodations. Knowing how to speak the local language is helpful but not always absolutely necessary. For example, Cab drivers don't speak much English so you want to have where you want to go written down so they can find it. There are tour buses that you can take often two story ones well appointed. But, be careful when you get on and climb those stairs to the top that you don't fall down when the bus suddenly takes off because the driver cannot see you at the top of the stairs. Same when he or she stops for you to get off. So, always hold onto the rails quite firmly.

The Electric Trolleys are nice but if you don't speak or read the local language navigating might be difficult. Same with the subways.

So, if you are more used to the more "wide open spaces" and not seeing a person for 10 to 50 to 100 miles like in the western United States you aren't likely to see that in Europe that much unless you are on the Matterhorn or Eiger in Switzerland or other Alps locations in the back country and even then you might see more people than you would at Yellowstone or even Yosemite National Park in California.
