We will be flying into Porto in early May and flying out of Lisbon 7 days later after spending a week in Germany where we will likely have been spoiled by public transit.
Should we stick to public transit in Portugal or rent a car for the duration?
I'm embarassed to say that while I've got Germany planned out in detail, I haven't yet done the same for Portugal :-(
P.S.: We're OK to fly into and out of Lisbon if that is a superior choice
