All that's going to happen is people will abuse DAS massively.The Fast Pass system worked well with the 3 passes on the App, especially if you knew how to use them well. We stayed at the Swan and Dolphin one year for a 2 or 3 nights purely to take advantage of the early entrance and the early access (60 days) for booking your fast pass rides. There was actually a point to staying on site with those perks but seems hardly worth it now.
The cost for "genie" is dreadful for families now.
We are thinking of going back in summer 2023 but the whole Genie thing puts me off going to Disney even though there will be a lot of new stuff that we've never experienced (Star Wars World, Tron, Epcot changes etc).
