We have a summer home in Bradenton (just North of Sarasota). I've found my DA 55-300 sees a lot of use followed by Pentax-M 28 2.8 (although I've had trouble with focus and softness with that).
Your message prompted me to set up a Flickr set... my first!:
Florida - a set on Flickr
Couple of things we enjoyed:
Tampa Lowry Park Zoo (45 min north)
Florida Railway Museum (20 min north)
Siesta Keys Beach
Busch Gardens (45 min north)
Tampa Devil Ray Game (45 min north)
Mote Aquarium in Sarasota
There is also a cool Classic Car Museum if you're into that.
