First of all, if you are traveling Europe, stick to Eastern Europe. Pretty much everything is cheaper in Eastern Europe. The food is a lot cheaper. The hostels are super-cheap. The transportation is super-cheap. Some countries I would recommend are Croatia, Prague, Bulgaria, Hungary, Turkey (technically Asia), Ukraine, Slovenia, and Poland.So here are a few tips:1. Stay in hostels.2. Travel by bus.3. Eat from the market 2 meals a day.Obviously everyone has a different way that they like to travel, but try to stretch your dollar. In Eastern Europe, a beer may only cost you $1.50. A meal may only cost you $3. Of course there are always more expensive options if you want them.Travel By Bus
Bus travel in Eastern Europe seems to be the cheapest for the most part. In the Ukraine, I took a 10 hour train ride for about $15, but usually buses are cheaper and more flexible. In my opinion buses are also safer than trains. The Ukraine train ride was at night and a little spooky. If you travel western Europe, the transportation costs get pretty steep. Some of the high speed trains might cost you $50 or $80 to go a couple hundred miles. In Eastern Europe, you will probably spend half or a third or less on the same distance covered.

In Slovakia, I stayed in a college dormitory for $6 a night. In Switzerland, my room was $30 a night. If you want to save the most money, it is a good idea to book your hostel ahead of time. So, you might be in Budapest heading for Prague. Checkout some of the hostel booking websites online. You can find out where the cheapest place to stay is online and book before you get there. Usually the rates online are cheaper than what you pay in person. Remember that many of the cheap hostels are also the most crappy hostels, so you will have to decide what you are willing to tolerate.Buy Food At The Market
If you are trying to save money, buy food in the markets or at grocery stores. Most hostels have cooking facilities, so you can shop and cook. If you don’t like cooking, the food can be dirt-cheap in Eastern Europe, so it might not cut into your budget too much.So, by staying in hostels, sticking to Eastern Europe, traveling by bus, and buying and cooking your own food, you can travel Europe on about $30 a day. For about $3000 you can spend the whole summer overseas. Oh yah, another advantage of Eastern Europe is you won’t see the hoards of tourists you do in the West. Good Luck.
