Hello. Ive researched my question and believe I understand. I just would like some conformation or advice.
I am an American citizen that backpacked Europe from Dec. 17 to Feb. 17. In total 62 days. Im thinking of going back within the next two weeks. Since I can stay in the Schengen Zone for 90 days, without a visa, I was thinking of flying into Madrid, travel Europe for 28 days, and then make my way to the UK/Ireland (out of the Schengen Zone) and travel a few more weeks. Im I correct? Its my understanding that I still have 28 days that I can still use in Europe without a visa.
