Hi all, this is my first forum post! Looking for advice on whether to spend one of my three days in the Lisbon area in Sintra, or really maximising Lisbon in full. From what I can tell, there is no shortage of things to see in Lisbon proper. Is Sintra an absolute MUST? It also looks amazing.
For additional context: I will be renting a car and driving from Lisbon to Porto after my three days in Lisbon.
Thank you!
