First it depends on how long you have,, how much money do you have,,and where do you want to go,, or see...... . If you have time.,, take the train to where ever,, you can ride 1st class,, over night,, i suggest it,, 2nd if its a day trip.... . . If you want distance and places to go and see,,,, FLY.... try easyjet.com..... I just did it during the winter olympics.... was cheap and fun and on time !!!!. . last ,,if you want to show off,,rent a car... but be prepaired to pay for it.. its expensive and most people dont own cars in europe just for that reason...... . If you have to,, rent a motorcycle,,, but,,,, be careful,,, you are NOT use to driving in the cities there,,,, they are and its dangerous for non residents to get anywhere......with out getting squished......... . Good luck,have fun.......
