they could also have kept it as your GAC states "guests can use alternative attraction entrance where available." There is a reason it is on the card & when explained to the CM (even though one should not have to each time), they should allow you.
There is one available, the wheelchairs use it. While they cannot change the lighting for those with low vision, they must either provide a guide or an alternate "lit" entrance for the guest, as per the ADA, of which Disney is not doing. That is not a gray area,that is black & white. In this case, it is black.......dark black to where you cannot see. I went to the MK today and did not even want to deal with going into the HM. Is it fair, no, but until they get things straight, I am not going to fall in the room to prove to them they are wrong
Most guests with wheelchairs are using the 'dark' area, not the way that used to be the wheelchair entrance before renovating (going thru a door in the stretching room or the room before the stretching room to the exit for boarding. Not going to the exit from the hearse area as was previously done.
Guests with wheelchairs can't be routed to the usual boarding area because it is not wheelchair accessible. They need to board at the unload area so the wheelchair or
ECV will be at the exit when they get off. That is why they are 'automatically' routed in one way and guests who can walk may be touted a different way).
The gray area is not
that accommodation needs to given, it's how it is given. People need to contact Disney and explain what is not working for their needs. The ride CMs and managers have to work within the barriers of the guidelines they were given. They are not at the level where they can change things.
It may seem very black and white to 'provide a lighted area or an escort'.
The gray areas are things like:
where the person who needs assistance waits,
what the conditions in the wait area are
how long the wait can be,
how is it determined someone needs an escort,
how a CM is notified of the need for an escort,
which position is the 'designated escort' - and how are they freed up
where is the person escorted to and is there a wait in that area
what are the conditions in that wait area
If the person is brought into the line, where and how
Some of those may have looked easy or not been considered enough when the new queue was opened. The things they set up may have looked like they worked on paper, but don't work well in real life.
It's all those things that get figured out later.
It happened in Pirates after it reopened after renovation. They actually brought some people's personal wheelchairs into line and then could not get it back to the unload area in time for the person to get off.
It happened in Small World when they renovated and were planning for all guests with special needs to enter one way with the rest of the guests. They actually closed the attraction again and redid the whole loading entrance/exit.
So things do get changed later as they get feedback on what the problems are.
It could be that what is really needed is a different stamp that explains needs better for people with low vision in darker areas. Alternate entry does not mean one specific thing and doesn't tell what type of entry the person needs.
The expectation is that the guest will ask for what they need, but WDW could do a better job of explaining what the access into an attraction is. They have nothing that says anything about lighting conditions, or even things like which attractions have moving walkways (which is why I started the disABILITIES FAQs thread in the first place.)
Saying 'low vision' may mean very different things to different people. One person may have sight, but see things only very close to them and not have much trouble with the dark. Someone else may have a lot of difficulty with transitions from light to dark, but be OK in dim light. Someone else may not be able to see at all in dim light and really can't go out at night.
And a CM who is working inside HM doesn't realize how dark it is in there because their eyes have gotten accustomed to the lighting. So, maybe some better education for CMs to explain that may be helpful.
(I am always amazed how bright it looks in all the areas of HM at night. I know they don't change the lighting. The difference is that my eyes are used to the darkness outside so, it looks relatively bright inside.)
