My husband and I are planning a tour of Europe by Eurailpass . We would be flying from Washington ,DC to London and start the tour there . We plan to see France, Belgium, Amsterdam, Germany along the Rhine, Switzerland, Vienna, then Venice, Florence then fly back . We have been to Paris and Rome so we could omit going there.We would appreciate any advice. We plan to purchase the Global Pass and take a 21day tour. Thank you very much.
