I have been to Orlando in July, hot and humid. However, it was the same hot and humid here in western NY. Now, would I go to Fort Wilderness and camp tent in July - no way. However, there are other options that would still allow you and your family to camp at Fort Wilderness with a bit more comfort. First and foremost, Fort Wilderness does have lovely air conditioned cabins; but, they are very pricy per night. There are several places that rent RVs (air conditioned) and will take them right to Fort Wilderness and set them up for you, teach you have to use the systems, and then when you are ready to leave for home they come and pick up the RV and remove it from Fort Wilderness. I do not know their name right off as we have our own travel trailer but you should be able to find out about them at fortfiends.net. This would allow your family the pleasure of staying at Fort Wilderness (and it is wonderful) with a bit more comfort than in a tent.
