<human>: Can you summarize the given text in a few sentences?

So I've been on quite a few vacations with my family but have never left the country. I finally got my first "big boy" job and would like to go to Europe in August of this year with a friend or two. I've always wanted to take part in La Tomatina.

Ideally I'd like to start in Amsterdam, visit some landmarks and "coffee shops", though I'm not sure where I'd go?

and I want to end my trip with La Tomatina in Buñol, Spain (which is the whole reason I want to go). 

Obviously my vacation would be limited to 10-14 days, which I realize isn't much time. I was told trains are expensive? What advice do people have for getting everything in order from across the sea?

I've just begun doing some research but seeing as how I am new at this I figured tips from fellow redditors would help get the ball rolliing!

and yes, I have a passport.
