10 nights in late May
Fly into Porto - 3 nights (get car for day 3 side trip to Guimaraes and keep for the next day and on) - Wed-Fri
Drive to Evora, stopping in Tomar in the middle of the day to see the Convent and Castle - 1 night - Sat
Drive to Comporta in the afternoon after seeing some of Evora - 2 nights for a little down time - Sun-Mon
Drive to Lisbon, ditch car - 4 nights - Tue-Fri, fly home Saturday
Day 4 is a long one, but my wife and I did far more every day in our trip last year to the UK.
Is 4 nights in Lisbon (which really means 3 full days) about right (with a side trip to Sintra)?
We could skip the night in Evora and add a day trip from Lisbon (adding one night to Lisbon), but I usually prefer to be my own tour guide.
It would be nice to add Coimbra and/or Algarve, but with 10 nights, it doesn't really feel like there is enough time.
