We're planning to visit Portugal in mid-March for about 10 nights. I was thinking to stay 5 nights in Lisbon and 5 nights in Porto. But after i read some articles, i'm thinking to staty in Lisbon 6 nights and 4 in Porto. Except that Lisbon is bigger and has more to offer, also look like that much more day trips can be taken from Lisbon. Is it correct? Any suggestion please?
Which 1 day trips from Porto worth taking? Guimarães? Braga? Something else?
Which 1 day trips from Lisbon worth taking? Sintra? Obidos? Evora? Tomar? Something else?
