I think even if the wait was 10 minutes it would be "worth it" to those that paid to get in front. If you can't get on the ride like Rise or Spiderman then even a "small wait" is totally worth it. If the wait is 45+ minutes then a 10 minute wait (especially with theming and as long as it feels like it's moving swiftly) you're probably going to think it's worth it for $10 to $15 a ride. I don't think it'll be anything insane like $25+ for each attraction. I think it'll be fairly "reasonable" like $7 to $15 for most rides. Maybe Rise will be $20, but again, you miss the queue and can't get on at all vs $20, it's going to seem like a good deal.
Also, once you hit those merge points the line seems fast. I don't know if it's honestly 10 minutes or not, but it seems to go by pretty quick as long as you're still walking and there are just a few times you actually stop moving.
This will be a key point though if wait times decrease in general. If RSR isn't 75 to 90 minutes but instead is like 40 to 45 minutes most time.... you can't be waiting very long in the paid line before it starts to feel not worth it...
