Fantasy & Spirit Class Ship Design Question

Hello,

Very random question about the Fantasy & Spirit Class ship designs. What is on these decks that make the portholes/windows not straight (see attached)? I don't imagine the actual floor you walk on changes slope like that. I've never sailed on either class, but the design always bothers the OCD Engineer in me when I see them in Port.

Thanks,

Jim

I believe those are the windows from the main theater/showroom. They are slanted downward toward the bow due to the tiered seating and stern-to-bow slant of the floors in the showroom (higher floors and seating toward the rear, lower floors and seating toward the front).

And the porthole cabins below have a great window seat that you can climb up and use your bed pillows for comfort.

I looked around in our photos and found one that shows parts of two of those windows in the showroom on the Legend. The arrows point them out - apologize for the relatively poor quality of the pictures.

Holiday Class also had the same thing going on.

Isn't the middle line of portholes the "Jungle"...where the deck does actually go up and down !
