Umm... not to rain on your parade, lauch, but this is a recipe for ruin. I know people who have followed that advice, who are homeless now. You either take care of finances like an adult, (like YOU and the rest of us do, no doubt!) or they take care of you very unpleasantly.
We've never taken our son either -- or been ourselves -- and we haven't been deprived of anything. It's pretty easy, particularly on these boards, not to remember that most people can NOT afford WDW or DLR, regardless of what they do.
Good luck getting to Disney, marcusjohann81. I hope it all comes together for you.
