Hello- this summer we will be doing a cruise from Dover to Rome. It stops in Portugal (which we have spent quite a bit of time in) and Spain. We've planned so much for London and Rome and know Lisbon and Porto really well; but havent done any planning for the 4 Spain ports. Please send any ideas for the ports below. Each has 9 or 10 hours there. Which do we 100% need a tour for (we prefer private/small groups tours vs. ship tours, so please recommend some) and which ports can we take a cab/Uber to do something close to port. Open to doing tours when needed but prefer to explore on our own. Thank you in advance!
Malaga
La Coruna
Seville (Cadiz)
Cartagena (Murcia)
