We are spending 9 days in Portugal, flying into Porto on Oct 6 and leaving from Lisbon on Oct 15th. We plan to spend 4 nights in Porto, with a day trip to the Douro Valley and then take the train to Lisbon to spend the remaining 5 nights, with some day trips.
Does this sound reasonable or is there another city or town along the train route to Lisbon that is a must see?
Thank you
