We are going there late July. I've never been to Florida in the summer, let alone that far south. What's the weather like that time of the year down there? Are the bugs and critters bad? Do I need to stock up on bug spray and SPF 80 lotion? What kind of fun things have you done there? There will be 2 adults and 2 girls, ages 16, and one boy, age 18. So family fun ideas are needed too. Thanks!
