RAP was CREATED for wheelchair users. It's the entire reason it exists, it's simply been extended to allow more people to use it.
Exactly. Let's go back say 25 years & what most people would have considered to be "disabled" then would have been someone in a wheelchair / unable to walk or stand for a length of time. Hence the disabled access via ride exits - a/k/a RAP, in it's early incarnation.
As times have moved on, more conditions have fallen under the disability umbrella, hence the demand for RAP has increased significantly.
Back when I worked at Towers, if you turned up at Guest Services [as it was then] in Towers Street with a hearing aid on and played up your hearing loss a bit, it was an instant red wristband for ride exit access all day. Ditto for a suitably bandaged up "sprained ankle". They gave the wristbands out like confetti. And this was in the days when [genuinely] disabled guests got half price admission too. At least Towers / Merlin now demand suitable evidence.
The Disability Discrimination Act changed a lot. You can't positively discriminate, i.e. offer half price admission, to disabled guests. They now pay full price, but get a free carer in for free. This is right.
With regard to the "lockout" time. On the face of it, yes, they should have to wait the equivalent of the current normal queue time before their next RAP ride. But think of the topography of Alton Towers - it's quite steep in places, so a wheelchair pusher is going to get knackered. When I worked there we would let them have a couple of rides via RAP in close succession, then politely tell them that's it, go away, come back later in the day. In 99% of cases it worked (this is relating to wheelchair bound guests).
I suspect the real abuse of RAP is coming from a minority of guests who are 100% able-bodied, but who have a condition that prevents them from using the normal queueline. RAP was always intended as "you are unable to queue for [whatever reason] so board via the exit, enjoy your ride, then move on and enjoy other rides" - not - "ride, re-ride & re-ride via the RAP entrance".
I am sorry if this post sounds harsh in places, but as an ex-Towers employee I have seen guests use the RAP system exactly as it was intended - and those who take the p155 big-time.
