Hi Sher and Crazy. Another option would be on the way to the space center, or as a separate trip. My DS9 and I stopped at The Lone Cabbage Fish Camp. We went on an airboat ride for approximately one hour +. The guide/driver was informative and had a welcome sense of humor. We saw a number of gators as well as other wildlife including an eagle and, although onshore, a few Hells Angels. lol. The restaurant at Lone Cabbage is also pretty diverse/interesting, offering turtle soup and gator burgers. The also have the usual burger-and-fries fare.
The Lone Cabbage Fish Camp also advertises a down-home barbeque complete with country music and dancing the first and third saturday of every month. My son and I are hoping to experience this "event" during a future vacation so this information is based upon advertisement and not experience.
If the opportunity is there, I would recommend giving the airboat ride at Lone cabbage Fish Camp a try!
All the best.
