Hi,
I am going to lisbon in two weeks and planning a day trip to Sintra and booked tickets for Peña Palace and Quinta Da Regaleira. According to previous recommendation, I am planning to take a Bolt or Uber from Lisbon and come back via train.
Do you recommend booking a train in advance? If so, which app or website did you use and when is a good time to get back to Lisbon after seeing the two landmarks and grabbing a lunch?
Thanks!
