Before I begin:
-I can do everything Disney has to offer (included with the price of admission) in 7 days if I wanted to.
-And why jump to Six Flags? They suck, they are the furthest away from the Disney model as you can get
Ok, it’s harder and more complex with more steps involved to plan a WDW vacation than any other park in this country. Want to restrict it to mega resorts? Still true, DLR and Universal Orlando way easier. Yes, DLR is easier, it has no virtual queues, you can get dinner reservations a few days out, they almost never sell out of single day park reservations, park hopping happens earlier, etc.
It takes more planning than any other vacation I’ve ever been on. It’s also over time gotten more and more complex, WDW is beginning to test my patience, I find less and less people making plans for trips. You can say the parks are crowded but are they really? Resort rooms aren’t booking fast enough they need to offer discounts. I suspect that raw attendance still has not returned to 2019 levels. Turning away/alienating customers is not a long term strategy to stay in business. Eventually you cannot push efficiency/profitability further there is a finite end to it. For the first time, I think we are getting close to that judging by recent events, especially if a recession happens. However I cannot and will not predict an exact date.
