If someone is truly very sick, perhaps they shouldn't be at an amusement park in the first place. That said, being truly very sick does not entitle one to experience more rides than those who do not need this system.
This is based on completely incorrect assumptions. You simply don't know what you are talking about. And even though I am sure you believe your statements, they are incredibly callous and I only wish you don't have to be on the other side of the equation and that you would so proudly make a public point about it makes me think it's not worth wasting my time to reply, but since you are incorrect on so many levels (and your assumptions are held by others who don't know better), I'll give it a try.
On many rides, the wait is LONGER - because you have to wait for a certain car so they can stop the ride so you can board, or you have to wait for an attendant to walk you in the exit because (see below) you have no choice but to use it. And for shows, the seating generally sucks - if you have a wheelchair, you are usually behind the very back row of everything (making it even harder to see for someone who can't sit up any higher to see the stage since people in front of you are often higher than a wheelchair can get).
People are so focused on a few big rides that they miss that the fact that EVERY SINGLE attraction has some sort of challenge for disabled people to board. That even the smallest, no-wait rides have different boarding processes. So yes, can you save time in line for Splash Mountain or RnR? Yes, but it takes us several times as long to do The Seas with Nemo, Haunted Mansion, etc. than everyone else.
In the end, when you add in all the extra time to find appropriate bathrooms (usually only one or two bathrooms in each park can accommodate a wheelchair and someone to assist them), the large increase in time required to do something like park hop, and just getting from area to area within the parks themselves, because of the accommodations on a few of the bigger rides, it just about evened out so you could logistically have a full day like everyone else.
They technically can experience other attractions during their "wait" time, they just have to use the standby system.
Which is impossible, since the majority of attractions do NOT allow disabled people into the standby line. So no, it's not "technically" possible, you really should pay attention to what people are trying to explain before you make your UN-educated judgement.
If Disney would make every single queue wheelchair accessible, you might have a point. People in wheelchairs would gladly wait in line like everyone else - IF THEY WERE ALLOWED. Most of the truly disabled people would like nothing more than not have to wheel into an exit against the flow dodging people leaving, or have to skip things like the Stretching Room because Disney won't allow it, or have to get dirty looks because they FORCE you through the Fastpass line or the exit.
I don't get what doesn't compute here - virtually every ride does this, we can't just hop on something with a short wait. I swear, people really need to think before they speak because if you had any idea what it's really like, you would be speaking much differently about the topic.
No, they just don't get the unlimited front-of-line access previously afforded to them.
As I've already outlined, completely false.
People like yourself making all these proclamations and spouting nothing but rhetoric have absolutely no idea whatsoever what you are talking about. That you all seem so resolute in your beliefs is sad and troubling. Yes, there are abuses - AND NO ONE hates them more than families like mine that have no choice but to use the accommodations or we couldn't go because Disney won't allow it because of how they have designed the attractions and their policies.
