As long as you stay in the areas where the tourists stay, or live close to the tourist area, you are as safe as anywhere else in the US.
I have lived in Orlando, FL my entire life. The weather seldom gets so cold that you need to have heat, and the average temperatures in the summer are upper eighties and low nineties. I loved growing up in Orlando, FL. Being residents, our prices for going into Disney World, or any of the other parks, were much lower. We could buy a yearly pass for the cost of one tourist price to the park. On those days it was too hot to do much of anything else, we would go to the park and ride all the fast rides, and those that have water involved. It was never a bad day in Orlando, FL if you had a season pass to the park. Some people ask if it is safe growing up in Orlando, FL. I guess it depends on where you live. When you live near the most magical place on earth, you would have to have good safety measures in place. A lot of tourists prefer to stay in Orlando instead of staying in one of the costly resorts inside the parks. As long as you stay in the areas where the tourists stay, or live close to the tourist area, you are as safe as anywhere else in the US. The tourist and business areas of Orlando are the safest areas. The city makes an effort to keep these areas clean and safe. With a crime rate of 58 out of 1000 residents, makes some areas of Orlando unsafe to visit. Just like any major city, it has its areas of crime.
