Need help planning a potential itinerary. Flying in/out of Madrid with a 5 day meeting in Barcelona. Have 6 days at end of meeting before leaving out of Madrid for home. Want to plan a couple potential itineraries. Have never been to Spain and want to see as much as we can without overscheduling time. Husband wants to go to Seville for at least a day but a long trip unless we can plan something along the way - also open to combination of train, car, flying. Will be able to do side trips near/around Barcelona during the 6 days in Barcelona as have some afternoon and full evenings to explore, take train to nearby cities, etc.
Any suggestions on possible itineraries we might take?
Thank you.
