I had the distinct pleasure of going to Florida last week, so here is a brief recap:
KCI, FTW!! Getting in and out of there is incredibly fast and easy. Luggage carousel, shuttle bus to the Economy parking lots, back on the interstate in 10 minutes, 15 tops.
Hotlanta - very busy airport, so kind of a drag if it's super-crowded. Decent food choices, had some Chik Fil-A

They have that subway thing if you have to change concourses and don't want to walk miles.
W. Palm Beach - lol, didn't know they even had an airport....but actually fllew there on a B757

Still a dinky airport so if you had a long layover you might die of boredom first.
