I mean...to an extant sure. But when you look at the numbers....Great Adventure really isn't losing as much capacity as people have made it seem. With this Mr. Freeze style station, Phantom Spire should be able to match the output Kingda Ka had at the end of its life when only 1/4 the station was actually used. Yeah Ka at its full theoretical capacity surpasses Phantom Spire but when was the last time that actually happened? Then Green Lantern was a capacity machine but hardly anybody ever actually rode it so it had limited effect. Flash was a poor choice capacity wise, without any sort of dual load that line was always going to be terrible, but that was a last second purchase so it makes sense that this happened.This would, for me, confirm my suspicion that low-throughput, high-spectacle rides are being installed to encourage Fast Lane purchase. I thought I'd never do it, but I broke today; I paid $499 for all-season Fast Lane Plus. With the prices getting more reasonable and less capacious rides being installed (lines getting longer), I suspect many others will give in and increase parks' income per guest tenfold by buying daily Fast Lane on the spot. I was at Cedar Point for three weekdays this summer and I never saw the posted wait under 90 minutes for Siren's Curse. AlpenFury's layout looks incredible, but I'm worried it also supports the idea of low-capacity headliners being a trend for SFEC
When it comes to Cedar Point....that park is just always going to be a nightmare when it comes to wait times because so many people visit the park. Siren's Curse was another last minute addition that to be frank....should've gone to a park more like Great Adventure. It's not a terrible ride capacity wise but it's not a ride designed for Cedar Point like all their headliners. Siren's Curse is a clone, that's the design that's supposed to be duplicated many times at mid tier parks, a much more efficient design could be made if they think Great Adventure needs it. But even when looking at the numbers....Siren's Curse had a lower average wait time than Steel Vengeance did the year it opened (by a whole 20 minutes too) so it's not really that terrible of a fit.
As a whole though, I doubt fast lane sales are at the forefront of these decisions. A lot of these rides were put in because of circumstance rather than a masterplan. The fact that B&M is in the mix still kinda goes against that idea as well, B&M while having issues makes some capacity machines. Alpen Fury is an outlier, I'll give you that, but Canada's Wonderland has always historically been the kinda testing grounds for Cedar Fair. Try a new model out there before you decide if you like it (the fact that they've blacklisted half the launch coaster manufacturers out there no doubt played a role too). Parks, to my knowledge, still make most of their money when you're out spending cash on the midways, that's why these restaurant renovations have been such a huge focus so far. Fast Lane is just a bonus.
