I was on the Solstice in July. The only area that looked tired was the pool in the Solarium. Every other part of the ship was fine.
As to the food, there are so many good choices in the MDR, you’d have to be a food snob or not appreciate good food to be dissatisfied. There were nights our group of 4 ordered extra entrees to share just to get a taste.
This was my first Celebrity cruise and I’m in the process of booking my next one.
The Solstice may not be shiny and new, but she’s intimate and welcoming.
