I don’t think it is from a ‘we’ll close rides to save money’ perspective, but more a lack of organisation in their maintenance department to ensure they have all the necessary parts for any unexpected downtime. And also a lack of managing their attraction downtime periods to reduce overlaps.
Rides have and will always need yearly maintenance, but in reason years MWs attraction seem to be needing more of it, for longer periods and more rides are closing at once. The impacts of the TRRR incident has definitely had an impact on maintenance periods, but they need to get on top of this and streamline their maintenance processes.
Rides will always have unexpected breakdowns from time to time, but the way to reduce the impact from this is to not have any more than two (whether that’s two main attractions, two kids attraction, or one of each) closed at a time (Obviously having Scooby closed for several years effects this, but in this case I wouldn’t include that in this formula). And try not to have the closed attractions next to each other in the park (for example, don’t close Doomsday & WWF at the same time because that makes one quarter of your park closed).
For a long time they would close Storm Coaster at SW from Feb to April because that aligned with shortly after when the attraction opened and they had to ensure they completed maintenance the same time every year. And to fix that they did two lots of maintenance so its annual schedule could be moved to the much more sensible time of the year (winter). So maybe they need to do this again with all of their rides at MW. This would mean there would be a year when some rides would need to close twice, but if that meant a better schedule for the years to come, I think that would be worth it.
So no I don’t think they’re closing their rides on purpose to save money, but I do think they are saving money by not investing in a catalogue of (backup) parts that they keep in back of house so that when rides do go down, they don’t have to order and wait for them to arrive. This cant necessarily be done for every kind of part for every ride in the park, but at least some effort should be made. But I don’t have any evidence of whether that’s fact or not, but whatever they are doing now isn’t working. They have become shit at managing their park, attraction operations and their maintenance. And if it continues like this it’s going really start to hurt their performance and most importantly (from their perspective) their pockets.
