My husband and I are walking from Porto to Santiago at the end of April. Coming from the USA I wanted to see as much as possible before we walk so we are stopping in Lisbon and Seville for a week and then on to Porto. I have found an ad for a day trip from Seville to Tangier and back to Seville. Great! I can ad Morocco to my list of "been there" or not? I have a friend that says I can be in Schengen countries for 90 days consecutively but if I leave at any time in those 90 days, I can not get back into Schengen countries for 90 days. She also said I cannot go to Gibraltar due to this rule. This doesn't sound right to me. Why would they offer a day trip if you can't get back in and doesn't seem like anyone outside of Europe would ever go to Gibraltar if you couldn't go back to your main airport for flight home! Please anyone that knows the rules I would be grateful for advice.
