Hi! We are planning on finishing our Spain/Portugal trip with eight to nine nights in Portugal in early October, coming from Seville Spain. We plan on three nights in Porto and five to six nights in Lisbon. We are trying to strategize our most efficient route between Seville, Porto, and Lisbon. Our preference is to end up flying home to California from Lisbon. There is only one, one hour early am flight from Seville to Porto by TAPA. It appears all other flights take anywhere from 5 to 7 hours. Our other alternative is to fly from Seville to Lisbon, then train up to Porto, stay three nights, then train back to Lisbon. That is a lot of transit time. Flying home from Porto is a possibility, but I am guessing it still would connect through Lisbon. A Lisbon departure to home would be better, given the additional time we have in Lisbon. Any thoughts?
Second question: Once in Porto, can we train down to Coimbra or Obidos, get off for a few hours to visit, and then take a later train into Lisbon? Otherwise, is a day trip to Obidos from Lisbon more realistic?
Thanks!
