I am planning a 3 week long trip from May 20th to June 10th and like everyone else, I want to do it all. My boyfriend and I want to cover London, Paris, Rome, Venice, Interlaken, Vienna, and Prague. We are unsure of the best ways to get from each place, the order it should be done in, and if we should cut anything out. I have been looking at budget airlines such as ryanair and airberlin as well as the train. I am completely overwhelmed. The websites I have looked at for train schedules and pricing are confusing and I wonder if raileurope.com is more expensive than buying directly from the rail provider? We are on a tight budget and hoping $1000 will cover all major transportation from city to city. Any suggestions would be really appreciated.
