• I am also wanting to visit Greece & Santorini, I'm trying to find the best & cheapest way to travel to these destinations without having to visit any place twice if possible. Have a month in which to travel. Thank you.

• Answer:

  Fly from London to Portugal using Ryanair. Use trains or buses to travel Portugal and Spain. Take the train from Barcelona, Spain to Milan, Italy. Then travel Italy by train, and when you're done take the ferry to Greece - there are a few different options, like Bari on Italy's East Coast to Patras, Greece near Athens. You take ferries from Athens to Santorini or other Greek Islands. From Athens to Prague, and Prague to Tallinn you might want to fly since trains and buses are very slow in Eastern Europe. Then get Ryanair back to London from Estonia or Latvia. You might want to cut that itinerary down - it's really a lot for one month. You'd be spending a lot of your time on buses, trains, and ferries, and you'd only have about 3-4 days in each county not counting travel days.
