I really enjoy cruises as one of three main types of holiday that my partner and I take.
To us, a cruise is a great way to 'sample' countries and destinations and to be made to feel special.
One of our ports was labelled as Seville. Cadiz is NOT Seville (which is about 50km inland). As the itinerary listed Livorno and Civitavecchia - why claim Seville when you are docking at Cadiz?
