If you decide you want to do something that looks like fun but costs money, then have it with you.  So if you take 200 for food, then I would say take another 150-200 for others.  Leisure, maybe going out and eating a really expensive meal one night just to try it, drinks, activities... clothes, gifts for others.

You can always bring the money back, but if you don't bring it with you, then there's nothing you can do :).

I have like €450, that's got to be enough for seven days, right?

..right?

It says you quoted me... strange.

Well, if that's how much you have, take it all.  Look around online and see if you can figure out how much you migh thave to pay for things that you need to go surfing (if you're planning on renting them and stuff).  From there, get a general idea of how much you should spend on things.  Like I said, you just want to go and have a good time.  Not spend your vacation thinking about money management :P.  I would probably do something like take 350, and bank of spending that, saving your 100.  That way, if you budget with less, it gives you the leg room of suddenly coming across something else you might like to do, right?
