I have three ideas. 1 it is a row of cabins that are not available for the public to book. There is a run like that on QE which are reserved exclusively for guest entertainers and other hosts etc.. They are shown on deck plans as a large white area. I had the last guest one before the run once and it was fine as you can imagine. 2. It is some kind of crew storage housekeeping area. 3 Looks like Bridge is on deck 8 so may be offices, cabins etc associated with Bridge.( Back in the day before Starlink I had a cabin next to the Bridge and the WiFi was much better than I had ever had before. Even had connection in an inside.)
