I have a business trip from June 2-9th and thinking of adding three days afterwards. The trip ends In Porto so should I spend the three days there? Or back to Lisbon where the trip starts and fly home from there. I was in Portugal 12 years ago and probably hit two days of highlights in both cities.
Which city would you choose to spend three more days in? I'll be on my own for this part of the trip. More questions to come after I decide.
Need to make decision so flights can be booked.
