The primary attraction for me on this cruise was Iceland, which I've wanted to visit since the early '90s. There, we docked at Akureyri and then Reykjavik and enjoyed one and three excursions, respectively. These provided a great sense of not only the country's incredible environment/terrains, but also a nice sense of its history, as well as its modern sensibilities politically, environmentally, socially, etc.
We totally hit the weather jackpot in Iceland, as every day reached ~60 degrees with plentiful sunshine 😎 This was not what we anticipated based on everything we'd read beforehand, and I traveled in shorts and short-sleeve polo shirts the entire time.
Ireland involved two ports, Cobh/Cork and Waterford. With only 8 and 10 hours available, respectively, we nevertheless experienced the flavor of these areas. The Jamison whiskey tour, particularly, was fun -- especially the tasting at the end. While we departed knowing there was so much more to see, this "primer" offered enough enticement to make us want to return for greater exploration some day. Also, the weather both days was again idyllic -- sunny and relatively warm.
The only clinker in the itinerary proved to be Scotland. With less than 7 hours in port (Greenock), we spent about 90 minutes round trip traveling inland to Glasgow. That excursion basically comprised a bus ride, a very minimal B/W photocopied map of the city center, and a "guide" who apparently didn't know how to use the bus microphone because he said nothing about the sights we passed en route. Beware the "on your own" excursion.
That said, Glasgow is a cool city; very cosmopolitan/diverse and filled with interesting architecture, both old and new. Weather-wise, it proved warm (mid-70s F) and humid, and it rained lightly at times, but not enough to spoil our journey. The city is crazy-hilly, similar to San Francisco, so wear the proper footwear if you visit.
Thanks for asking,
