S&W Florida vacation must see things from FL Natives?

[Wild and Free]

My wife and I are headed to south west Florida in a few weeks for a week long get away. As the title says we are looking for advice from natives on must see things we prefer non city non typical tourist attractions, we never go with plans we like to wing it as we go, after 15+ years of criss crossing the country it has never left us with a bad vacation yet. We are flying into Orlando and renting a car there. The only thing my wife wants to see is Busch Gardens the first day in Tampa from there we are planning to head south along the gulf coast and drive the whole Key highway and back to Orlando. So to you Florida natives we ask what your list of must see things would be in the area we are going to cover over a weeks travels? We want to give Florida another chance, we were there in February 3 years ago and were very disappointed, left ND at mid 30's, arrive in Orlando with mid 30's temps there too, 5 days there the first day we saw over 60 was the day we left it finally hit 70 and then rained, we drove to a relatives house on the beach in New Smyrna beach and went to Daytona and down to Cocoa beach and a couple days at Kennedy space center.
