The ship docks directly next to the center of the city and it's very easy to get around. We did take a tour to Ghent and the chocolate factory which was operated by the ship and was quite a nice tour. Ghent was charming!
Ship docked in Le Harve. My husband rented a car and drove to Omaha Beach. The rental agency was not convenient to the pier. Ship ran a shuttle to Le Harve which was outrageously priced $10 each way for a 5 minute ride. This port was not conducive to walking to town though and really not worth the price of the shuttle. There were several other tours, including spending the day in Paris, offered by the ship which were nice. We went to the Alabaster Coast and saw the cliffs which was quite nice and drove through charming Normandy countryside.
Toured Sintra which I loved and had lunch at Dos Cabritos which was wonderful and typical Portugese food. Visited the seaside resort of Cascais and then Lisbon. Lisbon is beautiful and worth seeing. Went to the end of Western Europe on this tour. Covered a lot of ground in one day. My husband used public transportation and he said it was outstanding. He took a train to Sintra and loved it!
Many taxi tours available at the pier. This is really the better way to see Gibraltar because most of the roads are single lane and if you are on a bus tour you end up having to walk up the mountains because the buses cannot make it up on these roads. There is a cable car but this also requires many miles of walking to see the apes and get to the top of the rock. Seeing the apes was a highlight for me. Our taxi driver seemed quite well acquainted with several of them and they sat on the van window. We also saw St. Michael's Cave and the tunnel from war used to defind the area. The taxi cost 25 euros per person but it's worth it. They have their own currency and it's difficult to find an ATM machine. Found two on main street and needed some currency for lunch and few purchases. Don't get too much because you cannot use it anywhere else.
The port where you stop is actually Cadiz. This is a quaint old city and the only way you can see it is on foot. We took the guided tour offered by the ship and this worked out well. It included a Flamenco show which was outstanding and a sample of tapas and Sangria. Bus first took us around the edge of the town and then we walked. The ship is docked about a 20 minute walk from the center of town but I was happy to have the bus and a guide.
