Would 9-10 days in Portugal be enough for Lisbon and Porto with a trip to Algarve region as well?
Say fly into Lisbon for 4 days, head to Algarve for a day or 2, and then up to Porto for the remaining time. Logistically is that doable or too much bouncing around? It'd be heading from the middle of the country to the southern and then all the way to the north, which seems dumb on the surface, but that depends on the trains I suppose. I have a tendency to try to squeeze to much in when travelling so want to make sure I'm not doing the same here...
