We always go the first two weeks in July. (This year too) I love it! Parks are open late, take the advantage of using later park hours. Sometimes we sleep until 10 swim, grab lunch, shop, relax and hit the parks later in the day. On the other days, we get to park opening fastpass all the big rides and leave around 1:00, go back to hotel swim nap and hit the parks again in the evening. You will have a great time. Use fastpass a lot, as soon as another comes available grab it. Dont forget to bring sunscreen to the parks to reapply. I take the face rub in kind to reapply to the shoulders and face. Remember, don't drink sodas you will be buying lots and lots of water to keep you hydrated.
See you there!
