Bruges (or Brugge) was an interesting city. We did an "on our excursion" ship excursion that was not really on your own for the first 30 minutes of the short time we had there, because they didn't trust us to find the bus on our own so we had to march to a rendezvous point at high speed (I was very unhappy with this because I am still recovering from double knee replacements done a few months ago). Our time there was limited because there was an issue with heavy seas in the morning preventing the pilot boat from getting to our ship to escort us to Zeebrugge.
In Bruges, we did get a chance to see the main squares, sample some Belgian beer and enter the Church of the Sacred Blood. Bruges seems a bit "touristy" and it was quite crowded.
We actually docked in Le Havre and rented a car for the day. We visited Bayeux, thoroughly enjoying the tapestry and the cathedral, then paid a visit to the small D-Day museum at Arromanches and the beaches of Gold, Juno and Sword. We then spent a couple of hours strolling around Honfleur before returning the car. Honfleur is extremely charming, with a small harbor and many nice sidewalk cafes.
We booked a private tour in Lisbon that included a photo stop at the Belem Tower, a visit to the Jeronimos monastery, a chance to taste the Belem custard, and a great city tour with stops at several viewpoints. We had a large van to ourselves and our excellent drive and guide was Luis. This was one of the highlights of our cruise.
We booked the "On Your Own" tour, which provided bus transfers from Cadiz to Seville. Similarly to the Bruges tour, there was this annoying march from where the bus dropped us off to a rendezvous point. We were here on a Sunday, so the cathedral had limited opening hours. The lines to the Alcazar and Cathedral were huge, so we just enjoyed a horse carriage ride and some sidewalk cafe time. Seville is a gorgeous city, full of great architecture.
Gibraltar was substituted for Casablanca during our cruise. We booked a ship excursion that gave us an overview of Gibraltar, including Europa Point, St. Michael's cave, the Barbary Macaques, and an overview of the city. Our tour guide made this tour better than most Oceania tours we have booked because of his sense of humor.
