<human>: Could you distill the essence of the text into 1-3 sentences?

I've read some AMAs about world travel but none really dealt with the region I wanted to visit and if it did it was only a short part of that person's journey. I'm planning to make the trip with a few close friends this summer. Since 2 of the 3 people going have relatives in Ireland we're probably going to fly into and return to the states from Ireland. From there we'll probably have eurail passes to travel with. From my understanding those are like 500-700 bucks depending on which one you get but they supposedly come with hidden fees as some stations will charge you a supplement when you travel on the eurail pass. Does anyone have any clue what these fees will be? Also how much should I plan to bring with me? I plan on staying in hostiles and visiting 5 to 6 different countries so what do you think I should budget for that? My expenses seem to fall into 4 main categories...Costs before trip, hostile stays, spending money, and miscellaneous fees (taxi fare, eurail supplement charges, etc.) What should I plan to spend on each?
<bot>: Wanna go to Europe. How much should I plan to spend on the trip in regards to pretrip costs, lodgings, spending money, and miscellaneous fees? Also information on eurail pass....
