Just jumping in here as we are considering going on this trip next year if there is one, just how long does it take to get there and whats the norm for overnight stops?
Hiya Andy, I'm sure I've said this before, but it would be great if you can make this trip one day!
I can't comment much on the journey though, I've never done it by road. I do know it's over 2,500 km (1,800 miles) and that's got to be the absolute minimum, in practice maybe more like 3,000 km or more.
My only comment is that kms in Romania will seem more like miles, in distance and speed.
The roads are slow here, narrow in comparison and with slow trucks, hills and twists and turns, it seems to take ages to cover any distance.
A 450 km trip I often do in the truck, can typically take me 7 hrs, averaging near on 60 km/hr, which in the U.K. would usually be miles for kilometers.
So that means from the border with Hungary, you'll need a full days driving to get to our patch. Between the U.K. and the border, you could be clocking almost double that average.
As Shayne has said, the Trans-European motorway (A1 - Autostrada) here is gradually coming together, but there's still major gaps in it. It does help, so don't be afraid to use it.
