Bugs are not a problem at the Florida parks. I've never thought about bug spray. Sun tan lotion, yes, lots of it, and I usually bring a face stick with me to apply more once inside the park. A lip stick is also a good idea.
Yes, bugs are a problem at Cedar Point. Usually happens in the morning. Ride MF in the front, and you can get plastered. I rode in the front one time, and was ok, but kept my eyes squinted. Then I was in the back of the park near Mean Streak, and people we're getting off the train in the trees where the station is, and they we're covered in the bugs. They we're running to get away from the train. Going up to CP at the end of this month.
