Hmmm, it sounds like the very best way for you to introduce fat lazy video-gamer punk kids to the world of health and fitness would be for you to become a U.S. Military Recruiter!!! In a few short weeks, a military Drill Sergeant will have them in shape, along with some respect and discipline to mind their elders.
In regards to planning Europeon travel, please visit the website of www.RickSteves.com. I was staitioned in Germany (many years ago) with the U.S. Army and my favorite place I toured was Neushwastein Castle (spelling is off a bit) in Bavaria. The castle is the same one Walt Disney modeled his trademark castle after. I found it much easier to travel by bus because of the many winding roads in Europe, rather than a train. Trains are great for going between adjacent countries (in a straight line), but not for pinpoint locations of destinations where access is best achieved by motor vehicle (bus).
