Family group are travelling in Europe in July and August 2008. Group consists of two seniors, one adult, two students and 1 child. Travel will be something like this: fly Oz to London, fly London to Geneva then sorties from Geneva home base (6 weeks) to Paris, Venice, ending up in Rome for flight home to Oz. Question is would it be more economical to fly Geneva-Paris, and Geneva-Venice or would some type of Eurail suit better? All suggestions welcome !
