I know there are lots of questions regarding travel to Europe this summer. I think I'm clear on entry from the US.
However, once we arrive in Portugal, we will be flying to Spain, then France, then Italy. I'm checking on the country-to-country requirements, but I am thinking the process is different because as a US citizen I cannot get the approved EU proof of vaccination card. So it sounds like I may be taking a lot of rapid tests during my trip?
I am really trying to understand and hope that all of you experienced travelers can help me?
As always, many thanks!
