I had 2 CMs say they too noticed that their rooms had AC set much higher than they're used to on recent stays. It's just weird.
High humidity is not great. You'd think with the AC on all the time that indoors, you wouldn't feel any dampness. At home, I always want to have windows open to help AC bills, but it's always 90-98% humidity early in the am (IL) when it's cool, and I don't want mold. So sometimes I have the air on just to combat humidity above 65%. We have dehumidifier but it's cheaper to run the AC.
