Can we get currency as soon as we get into poland or do we need some before we leave.
Get it before you leave, the exchange rate on, or near the border could be crap. Plus it,s handy to have PL currency as soon as in Poland so you can have a good meal stop (better grub in Poland than Germany). Also fuel will be cheaper.
We have 2 drivers and are hopeful that we can get all the way without needing a sleep stop.
As long as the co/driver sleeps on route. Once in Poland though, he may be needed to assist with over-taking.
No idea about the toll-roads/prices.
