I will add my thoughs... Although I have never been to Eastern Europe, I will add in that. If you're wanting to get trashed every night. Stick to buying your alcohol at liquor stores. Get yourself a big flask and carry it around with you to the bars if thats the route you want to go. Predrink at the hostel with your bought liquor, I'm not sure what would be the cheapest around those parts. Of course with the GBPound, most of the things would be cheaper than if I came with my USDollars. I feel like 600 would be plenty, just make sure to price your trip ahead of time(ie looking up the prices for all the bus/train routes, and hostel costs). You don't have to book now, but I don't know how many times a budget sheet has come in handy for things like this.
