Hi, I'm a French into minimalism going to Zagreb (Croatia) to see a pop starlette in concert I'm a fan of. I arrive in Albania and would go back home from Croatia (Pula, on the coast, if I don't annoy you too much with details). I'll be in the Balkans for 9 days and I want to optimize my travel and spend the less I can and enjoy the best of it. My ideas are:
- going to hotels at maximum 20€ at night (there are).
- travelling as much as I can by night so I can spare the cost of the hotel (like 25€ a night bus travel and I sleep in the bus).
- eating REALLY cheap things that are not bad for the health (like sardines, cheese, a little bread, a little saussage).
- drinking only tap water (I am an alchoholic so this will be a challange to me).
- not buying anything, just taking photos everywhere, walking on foot as much as I can (wasting calories, meeting local people (I'm a polyglot) and just having minimal clothes with me that I can throw away if they are really unwearable and buying second hand others.

Is it possible to make it cheaper?
Thanks guys.
