Hi we are going to Cascais in June with our 2 children who will be 2 years and the other will be 7 months. We are wondering about transfers from Lison airport to Cascais. What are the laws on child seats in Portugal? Will we be able to get a taxi with child seats or are we better getting the train? If we have to get the train, will we be able to take the children by taxi to the train station without child seats? Thank you.
