You are talking of hostels... youth hostels? In this case the withdrawal limit is going to be way up from what you will have to withdraw.
Which card are you going to use? What is the hostel rate? Remember that you pay fees for each transaction at an ATM. So withdraw a larger sum than just what you may need. It is the easiest and cheapest way.
Once you tell me which card you'll use, I'll lead you to a homepage for the different ATM's.
