On one of the older ships a couple years back our room was unreasonably warm. First, we thought it was because we were still in port.. then we thought it was because we had just come in from the hot. When we finally did contact the staff, they came in and measured the temp. The tech threw the thermometer on the bed. It must have been too warm because he walked over and opened the cabin door... Wait. I want the room to be comfortable with the door closed. They brought us a huge fan to use for the remainder of the trip and it did keep the room cooler, but it was not ideal. Of course, a good excuse to stay out of the room ๐
