Do most WDW guests live in an area with low heat and humidity during the summer that turns them into some type of heat phobic lunatics? I live near St. Louis and it is high heat and humidity from May to Oct. and it is morning, noon and night...no evening cool down....that's just when the lightning bugs and mosquitos come out...lol.
I do agree that it is society that has changed. People have no understanding of others feelings. It is very sad. Many people make no effort in getting dressed for the day...I can't tell you how many people on our flight were wearing pajama pants or yoga pants...that weren't appropriately covering everything as they were being stretched beyond measure.
Don't get me started on those who think that leggings/tights are pants and it's perfectly okay to wear your pajama pants to the store. Okay if you are in high school/college, but come on, after that, you just look silly.
