Hello, I recently was on a BtoB from Barcelona to Copenhagen on Quest from June 11-28, 2022 and we stopped in Spanish, Portuguese, French, Belgian, Dutch and Danish ports as well as Guernsey. I did ship excursions or wandered around on my own in all of these countries and there were no issues or restrictions leaving the ship or returning. The standard precautions, showing your cruise card and putting your belongings through a metal detector, were in place when you returned to the ship. As we all know travel regulations and restrictions can change very quickly. I hope this helps. Regards, Paul
