Done it only twice ever. Both times to Florida. One time St. Petersburg, another time to Miami Beach.
How often do you tolerate really hot (REALLY HOT) weather without turning on A/C?
A/C is only really used in office buildings in UK. Our heat becomes vile, with insufferable humidity once it reaches anything above 25 degrees Celsius. So, multiple times a year.
Edit - Not often.
How often do you get sunburnt even when trying to prevent it?
