You know I have been planning our first Disney trip since November. We travel a lot. Every six months we drive from Houston to Philadelphia to take my brain-injured son for medical treatment. The whole trip takes a little over three weeks. We have been doing this for 6 years now. As my son grew more stable we have tried to take side trips to add some stress relief. We have been to other parks, and historical sights. A good part of the time my son and I are sitting on the sidelines waiting because where ever we are is not accessible. Disney World is the first place I've read about where that will not be the case. He won't be able to go on every ride but there are many he will be able to go on. WDW makes an effort to be inclusive for everyone. For the first time in Dec. Edward will be like any other child and get to feel the excitement of rides. He won't be excluded like he is for many many other places.
We haven't been yet, but the fact they include children like my son in their planning, means they have me as a customer for life.

While I doubt we will be able to afford to go every year, I would not hesitate to go there if we could.
My advice to you is:
Never let someone steal your joy! If WDW makes you happy, go as often as you can, whenever your circumstances will allow you. There is enough stress in our lives, your entitled to some happiness.
