This is the central foyer of the Royal Caribbean's Radiance of the Seas. I took this early one morning which is the only time that no people are present. The central column is about eight stories high and is serviced by elevators and stairwells. In the evening this is augmented with a colorful lighting display. I found this perspective through a glass portal at the very top.
At the very bottom is a bar, the next up is a Starbucks, then a champagne bar and so on up the levels. There are game rooms, libraries, areas for lounging, each level is unique. Often we would lean against the banister and watch the band playing music below or perhaps watch a demonstration on cake making. Certainly there are things to do outside, but on an Alaskan cruise there is plenty to do indoors as well.
This is a small ship by todays standards but it's a sister of the first ship I ever saw, the Jewel of the Seas. I was and still am amazed that this type of space and architecture can exist on an ocean-going vessel. Yet to the truly big ships this is unremarkable. I'm a simple man, and to me, this is really really big. Getting on a bigger ship seems like maybe going to the mall with a hotel that floats. The sea is almost incidental.
Anyway, my impression of these ships is one of awe, how they build them is way beyond my ability to comprehend.
