Don’t take contiki tours – get some guidebooks and go yourself. I might suggest getting a Eurail Pass before leaving for Europe, which will allow you so many days’ travel on trains that you don’t have to plan too much ahead for itinerary, then take into consideration what you are interested in. History abounds everywhere. If you like medieval history, Prague is a good place to spend some time, as well as take in some very good concerts and visit the Mozart house. If you have not finished seeing all of the palaces and museums in Vienna, it is a good place to spend time visiting the Schatzkammer, Hofburg, Roman ruins, Neidhardt Frecoes, Schonbrunn, Mozart house and Belvedere for starters. Frankfurt will bring you into the commercial West, where you might take Rhine cruises to view a multitude of breathtaking landscapes with castles on the hilltops, sample **** in the many vinyards and visit some really pretty German villages that time has forgotten. All of these places will allow you to practice your German, too, but remember there is less of it spoken in the Czech Republic and Vienna has a marked dialect. If you only have a couple of weeks, you should not try to see too much, but pick a few main attractions that appeal to you, stay in Youth Hostels where you can talk to other keen travellers and get info on what to see and where to go from them, if not with them, as well as from the friendly people who run the hostels. Mostly, remember wherever you go, to have fun and enjoy yourself!
