There're also many campings there or places where you can pitch your tent after earlier permissions like f.ex. resorts on Pogoria I lake. Popular destinations as Dubrovnik or Częstochowa can have lack of accommodation in high season or the prices can get higher. In this case the best way's to find a couchsurfer. Other option can be asking any local parish for sleeping. Although it's free. It's in good taste to rest some amount of money for the church. Almost every place mentioned in the itinerary has at least one accommodation place.
Mentioned countries are very safe. Stray dogs can be problem in Balkans but most of them are vaccinated and sterilized. If you are bitten by the one, call the doctor! Ticks can spread many diseases as Lyme disease. They're quite common in Poland and Central Europe. Venomous snakes can appear in more remote areas, if you see a one, don't move. Wild boars are a problem in Poland but they mostly appear in the nighttime or morning. They don't attack till' you provoke them. If you see passing wold boar(s), keep calm and wait till they cross.
Sanitary condition of toilets in Central Europe and some Balkans countries are similar to Western ones.

Diarrhea also can occur in those mentioned places. The best way to prevent is not drinking tap water or free water in restaurants/bars. Health service in all countries's quite good, Balkan countries' health service (except Croatia and Greece) has lower standards, so the best way's to find a private health care.
