One thing you really wanna do is go to your bank and ask them if they have any partners in Europe, for example my bank is a partner with DeutscheBank so I dont get dinged a fee at all if I use DB If I use any other bank its 5 dollars per withdrawl......ouch!!!!
Or you can ask them if there is a plan you can set up like you pay a flat rate of 25 dollars a month for example and then take out as much cash as you want thats what my buddy is doing over here cause before he called the bank and straightend it out he would pay 3 dollars per withdrawl again that adds up!
You also probably wont be able to use your debit card to purchase stuff from vendors, my mate tried it a couple times but it wont go through so your gonna probably have to carry cash all the time!
good luck though
