During my Alaskan Cruise, the weather was not particularly pleasant. For the vast majority of it, it was cold, cloudy, and rain filled. As such, it was simply not a wise choice to roam around the top decks at night.
Right before we finished our cruise, however, the clouds cleared up so I took my chances and went up to the top decks in the evening. I expected to see some lights on the top deck and I did find some hanging lights going down the length of the ship. So I took photos of them isolated from everything except the sky.
