We had plans for a December trip to Germany and Austria … and are now frantically trying to find a plan B. We are wondering about going to Spain - and ideally would also drive for a few days into Portugal. We are a family of five - and highly comfortable driving in Europe (including in Italy) - and want the freedom to explore small towns. We all all vaccinated and will be boosted by the time of our trip.
My question is whether there are restrictions (Covid or otherwise) that would make driving between those two countries problematic? Do we have to quarantine or take multiple tests to enter / leave? Thanks much for any help!
