So you're saying if the line is already long, they should make it longer? I don't really understand. With VIP, you're not just buying a fast pass but a fundamentally different experience. It's a personal, premium, tour of the park so it'd be strange to not have front-of-the-line access for this attraction, it's basically the same as what they do in Orlando iirc. Including Express would just back up lines more so this is a win (and those aren't exactly affordable so the "super rich" comment doesn't make a ton of sense).
The alternative is an HHN 2022 situation where so many people have Express that the standby line takes like twice as long or more than what it should.
