This is our third time in Lisbon but first disembarking from a cruise so we agree with everyone that it's a great city. In fact we love it so much we'll be back twice in the coming year.
I already looked into checking the luggage at the station and going to the Tile Museum but as i mentioned, DH frets about missing the flight and since we'll be back in Lisbon it's just not worth his anxiety. Fyi, we have 2 checked bags and a rollaboard so using the metro to the airport is a last resort.
BTW, there was a taxi strike on Wed. to protest against Uber. So I can't call his concern unjustified.
Thanks for the suggestions.
