We are planning a 6 day trip to Lisbon with 12 and 15 year old children. It will be our first time in Portugal, but the we have traveled to many other countries in Europe and around the world. And the kids are good travelers. What would be a good itinerary? We don’t eat pork, will that be challenging? Is late February a good time to go? We want to stay in 1 location for lodging, but are open to day trips.
We were in Lisbon in February of this year. Not very crowded and the weather was okay.
We stayed in the Baixa area downtown and it did not take more than a couple of days until all the restaurant owners and waiters knew who we were. The people are so nice there.
I would probably limit my stay to Lisbon and Porto on your trip--going by train between them.
There are plenty of things to see in Lisbon. We were amazed how large their museums are.
And do not worry about your diet. They will attempt to fish you to death. And plenty of fast food places are available too.
In March of last year, I spent 8 nights in Lisbon. You might find my trip report helpful.

I was in Lisbon in early February 2024. It was a great time to go, weather wise. Cool in the mornings and evenings, sunny and mild during the day. It was surprisingly crowded, but nothing, I'm sure, like it is during high season.
