Company complained about our thermostat temperature

My husband and I recently had family visit from the northeastern region of the country. We live in the southeastern region of the country. We have been experiencing one of the hottest, most humid summers in history. We warned our family about the heat, but they insisted on coming to stay with us for five days. Five days may not seem like a lot of time, but my husband and I are used to peace and quiet in our home. There were two children who were very rambunctious, and the adults complained about the temperature of our thermostat. We have a smart thermostat that works really well to keep our house cool, despite the hot temperatures. The smart thermostat usually keeps our home at 74 during the day and at night time around 70-71 degrees. My cousin was complaining that she had to adjust to the temperature of the house because it was way too hot for her. I was surprised because I thought that 74 degrees is actually a cool temperature. I asked her what temperature they set their thermostat to, and she said they typically keep it at 68 degrees in the summer. I told her that there is no way we could afford to keep our thermostat at 68 degrees. Our electric bill is already quite high keeping the thermostat at 74 degrees. My cousin asked if we could turn the thermostat down during the day to make it colder. I turned it down to 72 degrees, but I refused to turn it all the way down to 68 degrees. I understand wanting to accommodate your guests, but they also chose to come to the southeastern region of the country during the hottest time.
