Floating Hotel by Grace Curtis
The Floating Hotel is the Abeona, a spaceship hotel touring the galaxy. It's definitely light on technology. The Abeona itself is rather retro, with lots of wood and paper and pneumatic tubes There seems to be only one woman on the maintenance team and we never really know many details of how the ship works, just that it does and has been doing so for decades.
Every chapter in Floating Hotel is written from a new character's POV. Most of them are staff or returning regulars, and each has a past, or purpose, that has led them to the hotel. We learn their backstories and see how they spend their days. The stories and characters gradually build a picture of the vibrant life on the hotel, while weaving in a few mysteries as the plot meanders along.
I enjoyed the book, right up until the end. I wish the mystery portion could have somehow worked out differently or maybe been worked through...
