Not sure which ports you're visiting or if you already went. We did the Jade Nov 8-Nov30-back to back. If you mean Spain we did Mijas out of Malaga and for Cadiz I did a walking tour which was perfect. If you are going to Moracco Casablanca with the Mosque is great. We did a tour to what they advertise as little Marrakesh-don't remember the town which was the worst tour. NCL gave us a third of our money back. But this depends on the guide. Gibralter we did on our own, just picked up a van with other people and mainly saw the apes which was such fun.
Let me know any other ports.
The Jade is the best!
