Europe by Bus (coach) or by car is a wonderful go on your pace trip. Experience the juxtaposition of old and new that is the hallmark of Europe. Alternatively, Eurail gets you around arguably more efficiently but certainly less charmingly
Go to Brittany for its megaliths, Cannes for the sea shore, Paris, the City of lights which is the heart of Fashion in Europe. A visit to Monte Marte is a must as a charming counterpoint as well as the Louvre and the Palace at Versailes. A drive through wine country is an experience not to be missed with the tradition of excellence passed down though centuries of family winemaking.
Travel to London, see Big Ben, Parliament, the Tower of London, but certainly do see a show in the West End. Travel by train, or car to France past the white cliffs of Dover to Calais in France.
If time permits, fall in love again in Como, walk or better yet boat around the lake where the stars of Europe come for vacation. Have a gelato, eat pasta and recharge away from the bustle.
