I am too but hate a warm cabin. On the last March Northern Lights cruise I did on Aurora in 2020, the cabin temperature was unbearable at night. On the coolest setting it was 26 C. I had them out four times to no avail. It’s more than likely you will be dressed for the outside on a cold weather cruise, so it’s even worse. I hasten to add I’ve been on twice since in autumn and it was fine. I fear though they will ramp the heating up in advance of the colder air as they usually do and it’s awful.
