I get that - but at the same time
Disneyland is even older than WDW and it generally is in better shape (not saying perfect but better than similar attractions at WDW) so it can be done
Maintenance is definitely a challenge and the time it takes. People always complain when rides are closed for maintenance
I wonder how people would react if they took the rides down more often or did like the first Monday of every month Splash was down or something. I know some could be done overnight and they could hire more people to do that but I don’t think that can fully deal with it
