Germany and ? Help me advise D on summer trip to Europe

<p>Munich is a wonderful city with a lot to offer. Berlin is another city steeped in WWII and German history. Plötzensee Prison (in Berlin) is the prison where political prisoners (including those who planned Hitler’s assassination) & members of the Resistance were held and executed. Berlin also offers the Museum Island where one can visit the Pergamon Museum & see ancient Babylonian ruins, such as sections of the Ishtar Gate. It is a fascinating city for young people.</p>
