If you’re going to Europe, and planning on traveling, rather than staying in the one place for the duration of your vacation, and you don’t want to spend a fortune, there’s two or three alternative ways that you can travel throughout the continent.
The first option would be to take what you might call the “traditional” budget alternative, which would generally be backpacking and traveling by train. Nothing wrong with that at all, and by using a pass on the trains (known as a Eurailpass, and available in the USA from [http://www.raileurope.com/eurorail/index.htm]) you can certainly reduce your spending, whilst journeying widely throughout many countries.
There are, however, a couple of down sides to this traditional “budget” planning.
First, whilst it can often be exhilarating and exciting to meet and travel with strangers on a train, equally, sometimes, it’s nice to have your own space to enjoy the journey, on your own.
Secondly, by definition, trains can only take you as far as the railway station, and railway stations are not always placed where you want them to be placed. In other words, if you have definite “target” places that you want to see, then you might end up having to take a train, then a bus or taxi (for who knows what distances) before arriving at your destination. This shouldn’t be a problem if the place you so desperately want to visit is in the city, but what if it not?
