Obviously I'm alittle late to the party here (been away from the boards for a couple of days) but I just wanted to share my point of view....for whatever it's worth
When we first decided to pursue the WDW Wish Trip for my Matty I also initially thought a WDW property would be a better plan for us than GKTW. Like you, I believed that staying on property would allow for us to be fully immersed in Disney and make the logistics of the trip (we have 4 children ages 4-9) much more managable. Plus, Matty is 'well' and wouldn't require special accomadations that I was sure many of the Wish kids did. After thinking it through however (and researching the GKTW experience) I realized that GKTW was indeed the right choice. I wanted Matty's trip to truly be "his"
Wish trip. We are fortunate to be in a good situation financially (partially due to fabulous medical insurance) and take many family trips over the course of a year. The more I thought about it the more I wanted 'this' trip to be different from all the others. Having Matty's Wish granted was not about the 'free' family vacation............it was about a very special opportunity, an opportunity for Matty to live the life of a VIP in a child's fantasyland, morning, noon, and night. It was the opportunity to experience a 'once-in-a-lifetime' week of wonder. He deserved that.
It doesn't matter how much money one has, the experience that GKTW offers can never be duplicated. You may go to WDW again. You may stay on property again. You may go to the parks again. You may even be able to plan your days at Disney so well that you rarely if ever have to stand in a line again. But you'll never stay at GKTW. You'll never be able experience that atmosphere. It's hard to describe. Personally, as melodramatic as it sounds, my family found it to be life-changing. It was as if a lightbulb went on in our heads. We are now planning yearly anniversary trips to WDW (barring unforseen circumstances) with time set aside for the whole family to volunteer at GKTW. I am now looking into volunteering for MAW myself. And my husband? Well he is in the process of starting a foundation in Matty's name and dedicating the proceeds to GKTW/MAW. I honestly don't think we would be in the same place we are today if we hadn't stayed at GKTW. I almost feel as if it were part of a 'larger plan'. But, I know, not everyone believes in such things.
Please understand that I'm not trying to suggest 'you' would be making a mistake by not staying there. I'm just suggesting you make sure you understand fully what you could be missing out on by not choosing to stay at GKTW. It was really only because I took the time to do my research and allowed myself to think about it in terms of the 'bigger picture' that I changed my mind. You, on the other hand, might very well look into it, think about everything, and still feel like on-property is the preferred way to go for your family. You just don't know what you don't know, if you know what I mean.
Anyway.....just wanted to share. For whatever it's worth
