An interrail trip takes you on a tour of Europe on train or boat for basic transportation. Extra fees are 12 GBP for a bed which has clean sheets and pillows and 1 - 2 GBP for a train reservation. Deck passage on many boats and ferries around europ is free but you must pay a 20 GBP supplement charge for fuel and use of the airline seats on which you can sleep watch a film and even listen to music on some of the ferries. I had a good experience with the ferries.I travelled to Paris then used my interrail pass to get from Paris in France to; Berlin and Dachau, Germany; Budapest, Hungary; Belgrade, Serbia; Thesseloniki, Patras and Athens, Greece; Pisa and Rome, Italy; Barcelona and Madrid, Spain; Lisburn, cascais and sintra, Portugal and lastly Bordeaux, Lille and Marsielle in France. I had a brilliant time for my whole journey; met loads of other people travelling with interrail, none of whom had had any problems with it. However there was always an amusing story to be shared which definately kept me entertained. I know i could not have experienced such cultural diversity and so many places with any other method of transport! check it out on www.interrail.com !! you won't regret it and in total i spent 650 GBP for the entire trip including my food, accomadation etc. trust me, you won't find this amount of travel and fun with such a tight budget elsewhere. Also, only speaking English for the entire journey was rather advantageous.
