To me, after visiting the clear problem is not RAP. I love that towers are inclusive to everyone especially with the disabilities they accept.
The problem, is when each person seems to have almost 5-6 others with them. Now, I appreciate they should absolutely have a carer or maybe two depending on the severity of the disability but when there's a whole family, and a second family of I assume further relatives or friends also standing in the queue (Something I saw at least 5-6 occurences of in my two rides) it becomes a little bit of a joke.
It's difficult to address the issue without being insensative, and I understand you don't want to not queue with your entire party and split up. However Towers needs to consider ALL guests, and yes that includes the fast track queue and the normal queue. RAP should provide equity, not advantage.
