Hello. We are picking up a car in Lisbon and traveling north to Porto. I would like to stop in Sintra on our way up the coast, but I read that driving to Sintra is difficult due to the traffic and parking, ie., it's better to take the train there from Lisbon as a day trip. I was hoping to skip that since we'll have the car and will be on our way up the coast anyway.
Hope I explained myself well enough. Thanks for any advice on this matter.
