<p>after college graduation, I went to Europe for 4 weeks with one of my roommates, so I’ll share some stuff:</p>
<p>absolutely, you need to prebook train tickets for overnight trains. There is an extra cost that the Eurail does not cover, just so you know. Some trains you can get on/off with the Eurail pass (like, if you wanted to take a day trip from Rome to Pisa, or spend the day at Versailles) with just the Eurail pass by using a travel day.</p>
<p>The hostels will generally have maps (or can tell you where to get one) and explain how the mass transit works in the city you are in. All the hostel workers I encountered spoke fluent English (not surprising, but good to know).</p>
<p>Make sure when you buy train tickets, that you find out what station the train is leaving from. Just because the Barcelona to Paris train goes to station X does not mean that the Paris to Rome train will be leaving from station X. There are multiple stations in the big European cities, and you do not want to show up at the wrong one. Additionally, the trains leave on time. If you are not there, you are not getting on the train. Make sure you allow enough time to get from wherever you are to the train station, and enough time to navigate the train station (in a foreign country and foreign language) to get to the track where your train will be leaving.</p>
<p>I used a hiking backpack. Don’t remember the specific one. It was a couple hundred dollars though. So I don’t know if that counts as cheap. Most people I saw had this kind of backpack. Please remember if you are packing shampoo in your carryon, there are rules about container sizes, etc. Of course, you can buy shampoo in Europe. Europe has all the luxuries of the USA (at least the parts mentioned in the OP).</p>
<p>I recommend booking your hostel for the next city before you leave the city you are in. That always worked find for my friend and me. There are multiple websites where you can search all the hostels in the city. Lots of hostels have a few computers in the lobby that you can use.</p>
<p>There are laundromats… we used them a couple times, but often just did some laundry in a sink, even though sometimes hostels specifically tell you not to do that.</p>
<p>Most hostels that I stayed at included the sheets/blankets in the price or charged a couple Euro for them. Definitely something you can skip if you don’t want to carry them everywhere you go.</p>
<p>
</p>
<p>Most of the hostels I stayed in didn’t have much in the way of lockers… sometimes they did, but then generally not big enough for your backpack. I carried everything of substantial value with me everyday (passport, cash, credit cards, etc). I didn’t have a lock and there was never trouble. I did see some people traveling with a bike lock, but I think you can just take a knife and cut whatever strap you put the bike lock through, so that wouldn’t do much if someone really wants your bag.</p>

<p>There is (or, was) a boat from Barcelona to Rome that takes Eurail… met some people in Rome that used it. Might be worth looking into if they would enjoy a boat ride instead of the train.</p>
