I will have two full days and change in Porto and four full days and change in Lisbon, no car, traveling with my 13 year old son. All in late March. I generally like to do some tours to get some history and lay of the land. For Porto because I have less time, I am having a hard time figuring out what to do. If I do a full day tour in the city and a full day in Douro Valley, then the only roaming around time we have is the day we arrive, or potentially the morning of the day we take the train to Lisbon. For Lisbon, I'm a little less concerned, but I'd like a day in Sintra, and a day or a half day in Lisbon. A few questions:
Is it a mistake to do two full day tours while I am in Porto? (If I do, we only have the evenings and the afternoon of the day we land free.) Should I do a half day in Porto and a full day in the valley instead? Or skip the valley entirely? As the valley tour is wine-focused, it may not be as interesting for my son, but I would be into it!
For Sintra, some of the tours try to cram in Cascais and Cabo da Roca ... seemingly maybe at the expense of some of the sights in Sintra itself. Cascais looked beautiful but a little boring and Cabo da Roca seemed not super interesting. Would you advise just totally focusing on Sintra, or am I missing something?
Is there a specific area I could get to for a day trip/tour from Lisbon or Porto that I should be considering? I know we are totally skipping the Algarve. Just not enough time/wrong time of year/of less interest.
Open to other suggestions ... we may try a short tuk tuk ride while we are there, but it doesn't necessarily sound comfortable enough to do an extended tour in, but again, if I am wrong, feel free to yell at me! Thank you!
