Just finishing up planing our summer trip to Portgual. Will be using public transportation heavily in Lisbon (day trip to Sintra), Porto (day trip to Braga). I know we have to buy our little one a ticket on the fast train between Lisbon and Porto, but what about the other trips around the cities and do Sintra and Porto?
In Lisbon we plan on zapping with the naveegante card
Thanks!
