I'm so looking forward to this trip! Will be spending 4 days in each city Porto and Lisbon. We can't drive so will be relying on public transport. I've done a bit of research on it.. hearsay some douro cruises will not be operating during may :(
other than douro valley, what other places would you recommend? other than sintra what must do and go when in Lisbon? Any local dishes and good restaurant to recommend around these regions - Porto and Lisbon?
