We are flying on May 23 from Chicago to Lisbon and onto Porto, arriving 5/24, at 10:30 a.m. Our return flight is from Lisbon on May 30 at 12:30. We are seniors and our daughter is accompanying us on the trip. This is a short visit!
We are exploring Porto on day 1 and taking a Douro Valley 8-hour tour on day 2. The rest is a challenge as we want to travel back to Lisbon and see Fatima, a beach town, and suggested must-see sights.
What are your ideas and advice?
