I assume you're asking where you could ride:
1. Key West and back next\same day
2. Marco Island via Tamiami trail
3. Snake Road (exit 49 off Alligator Alley, then north through reservation to Clewiston)
4. loop around the lake
5. Sanibel Island (near Ft Myers)
6. Ozello Trail, north from Tampa, never been there myself though, not sure if it's worth going there from wpb
