When I first clicked on this link I thought the request was for a DE-HUMIDIFIER HAHA whoops!
As other poster have said - the humidity can be absolutely smothering. However, there is a big difference between natural air temperature humidity, and cool-mist generated humidity from cool water. The generated humidity does not 'hang' in the air, so it is easier to breathe in to moisten the air passages/sinuses and such.
Natural humidity is more difficult for the human body to absorb through regular breathing because it doesn't have the same effect within the air passages.
So, while it does sound incredibly ridiculous at face value to increase the humidity in the thick Florida air, it makes sense from a biologic perspective.
We do not travel to Florida in June, July, or August due to the heat and humidity - we are more October, November, January, February people HAHA
We have been the last week of May first week of June - and the week after Labor Day in September - and those weren't bad, but the crowds were higher than our usual Fall/Winter trips.
For GREAT weather in the shoulder seasons - go to
Disneyland in California, February, March, April, and May are absolutely incredible - and we've been to Disneyland over Labor Day week before and while the sun was very strong there was virtually no humidity. We love Disneyland and California - can't want to go back in a few year!
