Are we really comparing Disney park tickets to Taylor Swift concerts? Those are events, in a certain location, only at that time, that sell out, whereas the parks are always in the same spot and open to anyone most every day.
Maybe she will consider Swifty+ and Individual Swifty Lanes to enable fans to skip standby lines for bathrooms and concessions. A Swiftpass if you will
Good points. Disney theme park quality could charge a lot more if they came to you like the fair.
Taylor Swift is a driveable event for a lot of people when she tours vs flying that a majority of visitors need to do.
Disney World as a place also needs to be profitable a decade from now and beyond. Where as an artist would like to be, but does not have to remain at the level she is at now.
