Serbia (...almost)

We left from Pecs in Southern Hungary for Serbia early in the morning. The border crossing to Croatia was a quick and friendly affair.
Whilst we were simply transferring through Croatia, it was an interesting place in itself - lush, and quite flat with quite good infrastructure.
...but 2 hours later, we were exiting it to go to Serbia. Serbia was a last minute idea for a place to visit. We left Croatia's border and crossed over to Serbia, where our passports were promptly stamped in, however the officials then advised us that our green cards (insurance) did not cover Serbia and that we would need to purchase it from them for €80 for a month. When we explained that only 2 days was required, they said that a month was the minimum. We decided to give Serbia a miss as it just wasn't worth it for that amount for just 2 days.
So, back we headed to Hungary to continue our journey via Romania.
We stayed in a town called Szeged, which again impressed us. So far, Hungary has been one of the most beautiful, welcoming and interesting places.
