Wife and I are taking our first trip to Europe and are going Spain this March/April. We're trying to make the most of our time and see as much of the country as we can while there. We're there for about 2 weeks going to Madrid, Barcelona, Seville and Granada. Spending about 3 days in each city, so wanted to see what RRS has as far as recommendations for the cities and what to do, and what to eat/drink while there. Also any transportation advice is greatly appreciated. Thanks in advance.
