I think it's more of a classist hatred the stereotype at P&R management is that WDW customers are all the 'Honey Boo Boo' and 'People of Wal Mart' demographic and the TWDC P&R management is more 'evolved' they vacation sorry 'summer' in Vail and The Hamptons and if they deign to visit FL it's South Beach behind a velvet rope.

It's going to take a massive culture shift to bring WDW back to what it once was, Also contributing is as
@asianway notes P&R is run by office drones who think 9 to 5 not hospitality people who love the hospitality lifestyle and its 24x7x365.25 demands.
