I see you're in Florida. I'm in KY, and it's pretty humid here, in the summer. If you get 2 hygrometers, and have 1 in the 'bator, and 1 outside the 'bator in the room where you hatch, it'll tell you whether it's safe to open the 'bator.
I keep my humidity in the 'bator about 45% for incubation, (which means I don't add water at all, unless we have a cool spell and the humidity drops) and between 55%-60% for the last three days, to hatch. My ambient humidity in the room was nearly 70%, so it was ok to open the 'bator to take out some chicks. It wasn't going to dry them out. Had the room humidity been lower than the 'bator humidity, I would not have wanted to open it.
I have to keep silicon gel moisture absorbers in the salt, during the summer, or it'll turn into a big soggy mess.
Wintertime here, is dryer, I'd be more careful about opening the 'bator if I set any eggs then. I don't know if Florida ever dries out enough to be concerned about it.
You might consider starting a thread asking incubation advice from people specifically in humid climates. It makes quite a difference.
