Debbie:
Just don't count on much, if any, fall colors, here!
Palm trees don't change, of course. The majority of deciduous trees may lose their leaves over the fall/winter, but rarely show any color.
The most color I've ever seen is along a stretch of Florida's Turnpike south of Orlando, where there's some slightly yellow slightly orange slight brown visible as I return from my annual Thanksgiving cruise!
Temperatures will be "just about perfect" during the day, perhaps a "tad on the chilly side" at night. So, you may want a light sweater for your evenings at a Square! Same as you'd want one in almost any restaurant anywhere!
