For me, the complaint is not about it being a 'greatest hits' ride, but about the fact that they refer to us as muggles on multiple occasions within said attraction.
The main reason being, muggles are not supposed to be able to see dementors.
As well, Dumbledore inviting muggles in violates the wizard's code.
THAT is what bothers me.
Take those few lines of dialogue out, make us all potential new students or returning alumni and it fixes all the continuity issues within the ride itself.
I will take this along with a butterbeer crepe and whatever butterbeer themed latte or just straight up coffee they can come up with.
