I did a grand tour of Spain a few years ago and I agree that the Spanish people are very friendly -- muy simpaticos. It was a fabulous trip.
Started off in Madrid, then traveled to Barcelona to see the Holy Family Cathedral of Gaudi. After Barcelona we headed due north to Rosas popping into Andorra and Perpignan France for a day. Then we went south through Valencia, Alicante, staying in Malaga, and visited Gibraltar. We took the ferry to Morocco and finished the trip in Granada, Cordoba, Jerez and Seville. The Alhambra gardens were magnificent.
I fondly remember this trip -- the food, the people, the country along with delicious wines, cavas and beers.
Spain has a lot to offer the traveler! OLE!
