Road Trip Suggestions

OK.. I gave this some thought and have come up with 2 ideas for winter season.
1. Fairchild Gardens just south of Miami. Heard some great things. Its like Longwood Gardens up north.
2, Return to Vizcaya so we can tour the gardens..
3. Everglades City. Airboats and Stone Crabs. Takes about 90 minutes or so going I75 to Route 29 south exit. Lots of fun.
