do yourself a favour, lose the 500's and 200's, you cant spend them anywhere over here. nowhere accepts them. Secondly, if you do go out for a bender, and happen to 'lose' a 500 you'll be pretty pissed off. i was.
Whores cost about 50 Euroa an hour in Spain, road whores are about half that. most of them are Romanian/bulgarians though, and look great from distance, but when you're close up, you'll be pleased you bought that spare paper bag with you!
Last summer I spent around 2000 euros in Ibiza alone for one week only (excluding the rental car I had for the month). Dunno exactly how much I spent for the 3 other weeks in Spain/France and I just dont wanna think about it lol
