This is a very layered and delicate issue, but one which Merlin had to sort out.
I'm going to ramble on a bit now...
The current RAP system was unsustainable. In the past, it had too many people faking evidence to use it. Then it had too many people using it. Then it had to become a pre-book system which people missed out on. And on park, it was wildly impractical for people on some occasions (the length of the RAP queue at rides like Hyperia and Vampire could be 30 minutes long, after having to have waited virtually). It wasn't working.
I'm aware that Merlin currently require people to have a Nimbus card to get a RAP, and it must meet certain requirements. The big uproar seems to be that 'Difficulty with Crowds' is now not enough to get a RAP. I will freely admit I know little about the Nimbus cards and how they work.
One of the biggest issues to my understanding is that every time Merlin have changed the RAP requirements, anyone who had already qualified for a RAP didn't have to meet new requirements. And that is the same in the current changes. That means that any changes don't address the current strain on the system, just slow down how much more strain it is put under.
Long long ago, the RAP system was a lot tighter than it is now for people on rides. You could only have one RAP group on a ride, and they would have to be sat in a specific row / seat. This was so staff could prioritise their evacuation in case of an emergency. Now that was really only necessary for guests with difficulty moving, so that could be relaxed. It was also not a sustainable way to do it with the increase in RAP users. That system is a far cry from the current system, where you can get several groups of RAP users be batched into a station.
As
@Jamesss said too, neurodivergence is more commonly diagnosed and recognised now. That's not to say it's more common now, simply that we are better at recognising, diagnosing and addressing it. Which is a great thing. I'm a secondary school teacher, and there's plenty of kids I teach who are neurodivergent; that presents itself in many different ways and has varying affects on students.
I've seen many arguments on social media treat neurodivergence as something which automatically means someone must be able to qualify for a RAP. Which is very very wrong. It's such a broad, umbrella, term which people are using wrongly. Any argument I see of people saying that the changes "stop neurodivergent people getting a RAP" I see as immediately invalid, as those people do not understand the terminology they're using, but think they do.
Now, here's the thing. If someone who is neurodivergent has "Difficulty with Crowds", that is someone who finds "crowded environments or queues overwhelming or distressing". As I say, I'm unfamiliar with how Nimbus cards determine that, but if someone gets diagnosed with, say, ADHD, and they don't like large crowds, could they qualify for having the "Difficulty with Crowds" mark?
If so, that doesn't quite match up - standing in a queue is very different to being in, say, a concert crowd, which might be the only example where they don't like large crowds. Yet they would qualify for a RAP if Merlin accepted "Difficulty with Crowds".
If it is harder to qualify for that mark, how is that judged? Is a conversation with a medical professional? How do they make the judgement? How regulated is that? Could one medical professional be convinced with a story, whereas another would make someone jump through hoops?
As I say, I don't know how it all works. But my concern there is, however it works, it's open to interpretation, a struggle to verify and something that is completely out of Merlin's control.
So now they're left with two options.
First is to accept "Difficulty with Crowds", which brings forth a large number of people on the system. It makes it unusable for them and creates further issues.
Second is the reject "Difficulty with Crowds", which is leading us to the situation we're in now.
By using the Nimbus card, they can't differentiate between people in that group, it's all or nothing.
I've seen people through social media suggest that by not accepting "Difficulty with Crowds", it is illegal as they're not making reasonable adjustments under the Disability Act. I don't know enough about that, but who knows.
Obviously there's wider issues here. Lengths of queues being high. Queueing experiences being not great. Address those and it is a net positive for all guests.
In my opinion, Merlin did have to do something, as the system was unsustainable. And whatever they did would cause backlash, and it's something they'd have to ride out. Whether this is the right thing I don't know, but it's a thing.
The biggest question I have though: Why is disabled access only an issue at the UK Merlin theme parks?
Other UK parks manage fine. Other Merlin parks, fine. Parks with worse operations, fine.
Yes, some parks are less disabled-friendly than others, but I've heard very very few negative experiences of similar RAP offerings at any other park around the world.
That can't be because 'Merlin operate badly' or 'They're too popular' or whatever, otherwise we'd see these issues
somewhere else, surely? So what is it? Is it that UK Merlin have a much broader, open remit than anywhere else? Is it a societal thing present in the UK? Does the UK have a higher level of diagnoses compared to anywhere else? There must be something.
