Samantha,
We have been to WDW in July a couple of times. It is not our favorite time, but it is sometimes the only time we can go due to the kids school schedules. The crowds don't bother us, we get up early to beat the ones who can't. Have you checked out Tour Guide Mike's recommendations for the summer months? It may help to have his assistance. I'm trying his touring plans for the first time for my trip. We also go back to the hotel to nap or swim when the heat seems unbearable. Remember to drink lot's of water and try not to push yourself too hard. This year we leave June 10th right after the kids get out of school. Hope you have a great trip.
BTW, I am in Gastonia too.... Small world after all, isn't it?
