Despite the 'price conditioning' of the past decade, I, and many other people I know (not all of which are enthusiasts) always felt that the VIP\Q150 pricing model was far too low, and ought to have been priced higher from the start, given the inclusions.
Originally the Q150 was 'just an entry' and as it progressed, the VIP started having other benefits - night entries and so on, without much movement on the price.
Those who expected to pay higher for what they were buying will stick around, satisfied the park has now priced itself more appropriately.
Those who focus entirely on the bottom dollar and not at what they get for that price (hint: they're the kind of folks who leave comments on social media saying things like "we paid $400 for a family of four and...") are probably more pain than what they're worth. The percentage they lose because the price was reasonably increased will be offset by the reasonable increased price paid by those who see the good value in the product on offer.
