When I started coming down to Orlando in my early 30's for theme park trips, I instantly felt happiness when I would walk from the hot outdoors into some over-air conditioned place. At the top of these memories is arriving at the Royal Pacific Resort at Universal. Coming in, feeling that blast of cold air... it felt like vacation. It makes me smile just thinking about it.
Now that I'm local, "normal" temperatures are all different. We keep the house at 75 during the day, and 72 at night. 70 or lower is "jacket weather." Any time we have highs around 80 and a nice breeze, that's perfect weather. Granted, June to September is when we also have high humidity, and it's the part of the year we would rather be inside. The myth that it's always humid is a lot like the one that says it's always raining in Seattle. It's a seasonal situation. Just last week, we were in the upper 80's but the humidity was under 40% (for reference, the inside of your house is probably 50%-ish).
Air conditioning in the summer is insanely cold in tourist spots. The theme parks are notorious for this, especially in attraction buildings, but even restaurants and hotels are like this. I should do a comparison with, say, the average Target or restaurant in non-tourist areas. If my observation is incorrect, maybe it's just my frame of reference to my happyjoy feelings.
I had the crazy cold AC feeling twice today while my family visited Animal Kingdom, and it made me smile.
