He has hemophilia. Poor little dude - he is cute.
I think it is great that MAW kids get to go and have a great time at Disney. If your 5 - and a MAW kid - your pretty much going to Disney!
However, that being said - many of these kids are not on deaths door when they walk into the gates of WDW. There are some though that look it - I saw one that was a pale little thing in her wheelchair at WDW, very thin and white, wearing a mask and blankets in October - she looked exhausted too. I'm pretty sure she was a wish kid. I felt like I wanted to just take her back to her room for a nap - her family was pushing her around at all times of the morning and night. But maybe that was what she wanted.
Anyway, you can qualify for a MAW trip by having any life altering condition or, at least at one time, a condition that was life threatening for you (a chronic disease, even if well controlled - something like hemophilia).
I think that mom is blowing this one over the top - I don't think that being a MAW kid entitles you to everything mom wishes or desires during your trip if you didn't plan for it. I mean, honestly - they couldn't spring for the party tickets after having their vacation paid for like that? Or at least asked MAW in advance for party tickets, just by doing a little planning? I bet they would have made it happen.
Even the little cancer kiddos have to be well enough to tolerate the trip (usually). It is not only for kids who are on hospice or anything else. Just - life threatening illness. So they could be recovering, have a good prognosis and doing well at that time, but still be eligible for MAW. We all just hear MAW and immediately drop because they are kids and sick. But still - the adults have to have some boundaries (and personal responsibility).
