wow
Having been to WDW in August without camping, I can only imagine how uncomfortable camping would be... It is hot and humid, put yourself in a tent and it is misery... There are lots of other ways to save money:
-if you are driving this is easier, but if not, pack a suitcase with nothing but a case of water bottles, you can get a 36 case for $5 instead of paying 2.50 a piece at the park
-bring breakfast bars or mini boxes of cereal for breakfast, if you are driving you can run to the grocery store and bring fruit as well
-bring fruit snacks and granola bars for snacks, one you won't hear "i'm hungry" every five minutes, two, it keeps cost down, three they aren't just eating ice cream and cansy all day, four, fed kids are happy kids
-have the kids do chores to earn Disney money so when they get there they know what they can spend and thats it
-designate ahead of time which days they are going to get treats so they don't keep asking until you finally cave
-have a garage sale or use ebay adn graigslist to generate some funds
-split meals. My husband and I always split a double cheeseburgr meal at teh counter service restaurant, it is more than enough food for the two of us and it saves us the calories
