One of the things I love most about traveling is planning the trip. I love to do the itinerary and decide how many days I will stay at each place. Europe was perfect to stay for a 6 month trip but we only had 20 days. It was the perfect length for this trip. I was exhausted by day 15 and living out of a shared suitcase can be hard. Most of the people I asked for travel advise said that I should to take it easy while we were in Europe and enjoy the places that we were going instead of rushing to see everything. I wanted to do this; however, how could I waste time if I had never been there? It was impossible to take it easy. I was fascinated to be there and the people that advised me to "take it easy" it was because they lived in Europe. On the other hand, I only had 20 days and my working schedule does not let me get away too often for so long.

I have been buying multi-City tickets for a long time. I think it does save money when you are planning to visit more than 1 place. Flying into one City and return from another just makes you buy 1 one-way ticket instead of a roundtrip ticket to return home. Traveling around Europe is very cheap thanks to all of the low-cost European airlines available. We flew easyjet and vueling to travel between France, Italy, and Spain. There are also good travel deals with RyanAir and depending on which county you want to fly you can find good prices flying AirBerlin for Germany, Turkish airways for flights between Turkey and the UK and so on. Be careful with the baggage fees since many of these airlines have a strict policy with bag weight and size.
We looked at train passes but they were very
expensive compared to flying. The only inconvenience that I found from flying was that the airports are usually outside the City and many hours of your traveling days will be spent getting to and out of the airport. The security process was relatively quick and painless all over Europe. I will definitely consider buying a rail pass next time at least for some of the itineraries. The stations are usually centrally located in the City and hopefully the scenery should be a lot nicer. The only train that we took was the
EuroStar between London and Paris. It was 2.5 hours versus the 1 hour flight but, if you consider the travel times to and from the airport it does take you a lot more than taking the train.
Trains between France and Italy or Spain are usually overnight rides. If this is the situation, a 2 hour flight plus transfers from the airport would be a lot quicker (and cheaper). However, if you consider spending the night in the train it would save 1 night of hotel it might just be the same.
On my future trips to Europe, I will save 1 day at each destination to "take it easy". This probably means that I will sit at a cafe for a while and people watch or, if the weather is nice go to a nice park and do a picnic. I can't take it slow every day when I'm excited to see a new place. The double deck bus is also a good option because it facilitates getting to the top attractions without getting lost.
On my list of places to visit in Europe are Berlin and most of Germany, Prague, Turkey, Greece & the Greek islands, Switzerland, Austria, Italy (Milan, Florence, Pisa, Tuscany), France (Bordeaux & the French Riviera), and Southern Spain. I would go back to all of the places that we visited if only I had enough vacation days and frequent flyer miles!
For now, our next trip is to Colombia in less than 4 months to get married and to Hawaii for 10 days for our Honeymoon. We are still deciding which island will be our Honeymoon destination but planning is one of my favorite parts of the trip. I will be gone from work for 3 weeks. If I don't get fired for asking for so many days off, our following trip will be to Ecuador to visit my boyfriend's family. He hasn't been there in almost 2 years and if it was me I would be homesick. It does not matter where I go I have the same problem every time I go on vacation is that I come back more tired than when I left. Maybe the vacation I need is an all-inclusive resort with nothing to do but tan and read in a hammock. Maybe in 2012 for now I will be thinking of all the things to do in Hawaii :)
