Royal Caribbean | Radiance of the Seas 2023 | Room 7002 | Room Tour | Thanksgiving Week 

I think HVAC is shared by all rooms on the same deck and section. Its not a feature of a room.Only the dial belongs to the room but it controls the amount of air individually. The temperature is determined by the heat exchangers out in the hall behind the crew only doors. We had the identical 7002 on Radiance's sister ship Brilliance and the under bed space was perfect for two full size suitcases and two carry-on rolling suitcases. but we had to insert the under the bed then turn them 90 degrees to fit all. or we could have had the steward split the beds and put them in from the side. The ship was built in 2001 and has been refurbished twice since then. So not "old". The switch is a simple, reliable mechanical switch, called a "rocker switch"; available for under $5 at big box building stores everywhere built to modern electric code standards.
