The case for self-drive
Self-drive offers independence and, on paper, lower cost. Portugal's motorway network is modern and well signposted, Portuguese drivers drive on the right, and international car rental companies operate at Lisbon and Porto airports. Travellers comfortable with European driving, who enjoy navigating and who have flexible plans, can cover the coastal cities and main towns without difficulty.
For a coastal holiday centred on Lisbon, Cascais and the Algarve, self-drive is often perfectly adequate. The distances are short, the roads are straightforward and the attractions are well known.
It is worth acknowledging this honestly. A private driver is not necessary for every trip to Portugal. The question is whether it is the better choice for a heritage journey specifically.
