My main question is about the Balkan flexipass, as i seem to find a lot of contradictory information on it.

I'm currently in croatia working, but they kick me out of the country on nov, 30th, and i have a flight booked from timisoara in romania on dec 16.

so, i have two questions. firstly, my rough kind of plan on how to get from zagreb to timisoara is as follows:

zagreb to sarajevo to mostar to kotor to beograd to timisoara, with possibly a trip to cluj or oradea if there is time.

do you think this is feasible in a little over two weeks?

secondly, i was looking at rail travel in the balkans and i know buses are often a better option. however, there is a good trainline from sarajevo to mostar and also from kotor (well, from Bar/Podgorica) to belgrade. and then a very slow train to timisoara from beograd.

however, the trains are not super cheap, but i noticed there existed a 'flexipass' which i could use in montenegro, serbia and romania, but not croatia and bosnia.

so....main question is do you think teh balkan flexipass is worth it? and also, on the serbian railways website, it has prices for second class tickets, but other research, including on raileurope, gives options for first class only which are significantly more expensive. considering i am going to be very limited in funds, i need to plan this a little bit carefully....

ok, enough questions...
