If I travel from Northern Europe to hot places, the first thing I have to do in the hotel room is turn the temperature up about 5-10°C. If it's 30°C outside, 25°C is a reasonable room temperature. I don't want a shocking transition when I go in and out. Last year I visited a place with almost 40°C outdoor temperatures, and I set the car AC to 28-30°C.
