Best keep an eye on what paperwork will be required. We have two Euro trips planned for this year, don't want a last minute panic, I really can't see anything changing immediately the eegits agree on sumert.
We only started Euro touring after the kids got to an age when they could be left to trash the place while we were away. This was mid 90's, green cards were still issued then, I remember few years later phoning for one & being told, "You don't need a green card anymore, all the countries you're covered for are now on the back of your certificate". The RAC said we needed the IDP back then, that fizzled out soon after & only applied to non EU countries. Of course that may all be bollux, info' was all a bit vague, much of it conflicting.
Been nice & easy in recent years, mostly down to the Euro money, pre 2000 it was a real pita getting cash as we entered each country then getting rid of it as we left, six countries on route to Italy. Sometimes just for one night, nothing planned.
