We have stayed in that room , 8534, on the sister ship the Wonder. We nick named it the "triple wide" as the verandah is the length of 3 regular verandahs. The other cat T suites have verandahs that are double. I think the room is the same size as the other cat T suites, but at a different orientation. The orientation of the room is more parallel to the ship vs perpendicular, if that makes sense... The murphy bed is located in the living room vs the bedroom in the other Cat T rooms. We thought it was a great room.
We did not get much elevator noise at all. We did get some early morning chair scraping from above (but honestly, you will likely get that in all of the rooms on deck 8). It woke me up but I am a light sleeper, but did not wake up DH, the baby or preschooler.
The closets were huge. You can see there is a little jut out right next to 8536 and that is extra closet space.
Enjoy your cruise!
