Crowding has been blamed on:
1. FPs: FPs change people's position in lines. It doesn't get rid of lines. You want to argue that it creates winners and losers in the queuing game, that's a fair argument to make. You want to argue it creates longer queues, I am 100% unconvinced.
2. Understaffing: Still waiting for someone to tell me that years ago, besides shortening the hours and putting big rides under refurbishment that WDW never reduced capacity by reducing staffing in the off-peak periods. Yes, understaffing in this year when there is no off-peak times anymore is a bad ops decision and we should all complain. But were they purposely understaffing this Easter week when every line had hour+ queues? Can't blame that on understaffing.
3. Increased attendance: And those who keep blaming FPs or Understaffing, and, at the same time, keep ignoring that in just 10 years, the MK gets an extra 3 million people per year is inconceivable. When people propose theories without accounting for that, I don't know what to say. You can't argue with willful ignorance.
