Hi, This probably sounds like a silly question, But I tend to be always bringing more clothes than my family needs, and have been known to forget something important we need for the area we're traveling too. This is a long road trip for us, TN to Key West and we're driving all the way. Two adults and two teenagers. When we get there, I sure don't want to go out looking for someting I forgot...again! I know it will be hot and humid..but how hot? First time there any suggestions would be great..Thanks!
