We cruised on the Celebrity Infinity, a 21 year old ship in July of 2022, and the Apex in Dec in 2022. Everything was outstanding and the food was great. The surprise was that the buffet in both ships was marvelous, perhaps even better than the four main dining rooms. However, we never had a problem with the restaurants. Service was excellent and food very good.
On the Apex, nobody was checking if guests were washing prior to entering the buffet. And fewer mask which is a concern for us. We take precautions when we feel necessary and are covid free.
