My mother has family in Spain and I was seriously considering going there for about 7-10 days. Although I personally wouldn't mind traveling alone, I can't help wonder if this is a smart/safe idea for a 22y.o. female to discover and travel around a country like Spain *alone*. While they live in Madrid, I also wanted to visit other cities and possibly go to Portugal. Has anyone had much experience traveling alone internationaly? Thoughts? Opinions? Advice?
