i´m going to visit krakow, i´ve always wanted to go there
And if you´re also going to poland you should go to gdansk near the coast, it´s absolutely beautiful!
I think so to, the first few nights could be nice to have booked a hostel... I´ve thought about maybe bringing a tent but I´m not sure yet, because I´m travelling alone and maybe that would be to lonely...
but cheaper. And of course I can use the night train to save time and money.
I´m going to stop between greece and poland but I havent decided where yet... Serbia is one of my favourite countries so I think I´m going there, and maybe Croatia or, as you thought, hungary.
