We're leaving for Madrid the end of March and traveling through France, Italy, Austria, Germany, Brussels, back to France and leaving out of Frankfurt the end of May. Traveling via rental car.
Do I need to fill out the EU passenger locator form or any other country-specific passenger locator forms other than upon arrival in Spain?
Are there any potential issues with Customs (either entering Spain or traveling around Europe) with us visiting so many countries? I assume we won't run into Customs on the highway at the country borders? We're triple vaxxed and have our CDC cards.
