We are a USA couple in our mid 70s, who are fairly well-traveled but this will be our first time in Portugal. We ideally would like to travel by rail (and cabs if needed). We will be coming from Ireland where we will be visiting family, and will be returning to the USA. I would appreciate any suggestions on the following itinerary, and, in particular, what might be omitted if we were to shorten the trip by a day or two. We like ambience, culture, natural beauty and beaches. ideally, we would stay in a few bases with day trips. This seems to work for Porto and Lisbon, but I would appreciate suggestions on days 8, 9 and 10. Thank you for any thoughts and suggestions.
Day 1. Arrive in Porto at night from Ireland and transfer to hotel. 3 nights in Porto.
Day 2. Porto sightseeing.
Day 3. Day trip to Douro Valley (do we need to arrange this before)?
Day 4. Fast train to Lisbon. 4 nights in Lisbon.
Day 5. Lisbon sightseeing
Day 6. Day trip to Sintra.
Day 7. Day trip to Cascais.
Day 8. Fast train to Algrave. 1 night in Lagos. (Is this the best base? We would like to avoid crowds, if possible).
Day 9. Cab to Salema. Beach in Salema.
Day 10. Spend most of day in Salema. Spend night in Faro in preparation for flight to US.
Day 11. Return to US from Faro
