Cascais Portugal is a beautiful coastal city between Lisbon and Porto, with world class surfing at Ginsu(sp?) Beach, close to Sintra’s ancient castle, dating back to the Moors. A much more laid back place than Lisbon, but you can hop a train and be there in no time if you are looking for a more active nightlife. Family friendly as well.
Hoping to be in Spain summer of 2021 when a choir my daughter sings with will embark there. Curious if steelrgirl is a ‘Burgh thing?
