Florida is mostly known by tourists for Disney World, and thus not many people know about the other treasures there. However, after visiting Florida around 15 times in my 16 years, I've learnt that there's more to the Sunshine state than a single amusement park. Here are a few other places to visit in Florida instead of Disney World.
St. Augustine, Florida
For this one i just said the town because there are quite a few things to do here. That includes: Castillo de San Marcos, a small pirate museum, the oldest wooden school house, and a variety of shops. Castillo de San Marcos is one of the oldest forts in the United States and is also in walking distance from the shops. The others are a bit more self-explanatory.
Kennedy Space Center
Here you can see space shuttles, rovers and learn about what it takes to send someone or a rover into space. It also has videos of astronauts talking about their experiences.
Safety Harbor
This is another small town, in it is great food and little shops to walk around to, Whimzeyland, a 300 year old oak tree, and in the hotel are natural springs - said to have healing powers.
Congo River Mini Golf
This mini golf place is a personal favorite of mine and its become a tradition for me to go here every time I go to Florida. It has a little scavenger hunt while you are golfing and if you find the correct things, you get a prize. There's also an arcade and a place where you can "mine" for gemstones. They have alligators that you can find and if you are brave enough - hold.
