Neuschwanstein Castle- few things you should really know about it besides the Disney aspect. It means 'new swan stone' in German and isn't too far from the original. And ... the guy that built it (King Ludwig II) was quite the character. Look him up ... great place to visit :)
Wow! While on a trip, send yourself a postcard every day from wherever you are and write what you did that day on it... Then bind them when you return to have a journal of your trip. Complete with photos, stamps, and a run-down of each day's events!
