I am traveling to Portugal for a conference in July and booked an extra three days at the end to just enjoy being their. The conference is in Palmela, and I was hoping to get some recommendations on what to do with the extra three days. Initially, I had considered going up to Porto, but now I am wondering if I should stay in the Lisbon area.
Option 1.) After the conference, stay in Lisbon (where I am flying out of) and see the city as well is Sintra.
Option 2.) Try to see Lisbon and Sintra during the conference (it is a week long, so there will be some spare time), and then travel to a different location for the last few days before coming back to Lisbon to catch my flight home.
For ease of travel, I am leaning toward my first option, but I am not sure if there is enough to do or if will get bored. Is three days too long for this, or is it just about right? I am liking the idea of not having to travel back to Lisbon to catch my flight... I am also open to recommendations that are not listed above.
Please let me know your thoughts! Also, if you have specific recommendations on things to do in any of these places, please feel free to list them!
