My husband Paul has been invited to attend a conference at at the university in San Lorenzo de El Escorial (which is about 50 km north of Madrid) for 5 days at the end of July and I will be tagging along. We are planning to take an additonal 5 days and travel around Spain. We're having difficulty deciding where to go, given that we don't have much time. We wouldn't mind spending a couple of days on the coast and a couple of days touring around. Does anyone have any suggestions as to where to go? Also would it be better to take internal flights or the train?
