In defense of WDW camping in July...
Now hold on. Let's think this through. I agree..camping in July sounds like a horrible idea. However, my father and I have managed to pull it off with a little extra planning! In fact, we did it for a whole week!
Many moons ago my father and I camped at Disney (in real tents!) at the campground in JULY!!!! It was my 13th birthday present.
During the day we went to the water parks or participated in some kind of non-park activity that would keep us cool and away from the crowds. We rented the little speed boats (being on the water and getting splashed was nice), horseback riding (covered by the shade of the trees), or went swimming! The best part of these activities is that they weren't very crowded. Crowds make the heat SO MUCH worse.
We also made HEAVY use of the waterparks. I don't know if the trip would have been possible without them.
When afternoon storms were on the radar we went to the movies at Downtown Disney or a meal we knew would take a while. Everyone was waiting out the rain in walkways and we were feeling refreshed in the cool theater!
You can also take advantage of the in door theme park in Downtown Disney. We didn't do this but it was an option.
This was also the trip where we discovered the ESPN bar on the boardwalk. We were still able to relax for a while, eat something, dad had a few drinks, and we stayed connected to baseball standings in the days before smart phones. If you're not into sports, its still an okay option. If not, I'm sure there is another place in the World where you can sit for a while and just enjoy the day.
In the evenings we went to the parks and they were cooler and less crowded. This was during the days of the E Nights (best idea EVER) so we had plenty of MK time. Take advantage of early morning or late night extra magic hours so you won't be crowded OR under the blazing Florida sun at "high noon."
I kept a little battery powered fan in my tent at night and that helped too. I also seem to remember taking an extra shower or two here and there during the day.
To make a long story short, it can be done!
You just have to navigate to locations that will be shaded or on the water and away from the crowds. The extra activities cost more, but we saved so much money camping as compared to staying in a room.
We also spent a week in the World so we weren't in a rush to get everything accomplished in one weekend. We had time to putt around.
Also, we had been going to Disney our whole lives (Florida family!) and never done anything except the parks. It gave us an excuse to explore some shadded trails, try new dining, and to rent those little silly racer boats. That was great fun.
Then agian, I'm a Florida girl. We were both born and raised Floridians (living in Miami at the time), so maybe the heat didn't bother us as much. That's just something you'll have to consider. You can always abaondon ship if it gets too rough.
You just have to take into account your tolerance for heat and flexabilty in planning.
Honestly, it was the best trip I ever had at WDW.
