I will be traveling to Spain following my "Week in Portugal" trip with Tauck next month. I have checked the Covid-related entry requirements on line and find them very confusing. I can't tell whether I need to complete the on-line health form or whether my CDC card showing two vaccinations and two boosters will be enough. I've also gone on the US Embassy website for Spain and do not find it helpful. Has anyone been to Spain lately, and, if so, what did you have to show prior to entry into the country?
