They dont see a guest retention problem. For every 2 of us that are ready to walk away from pre-planning vacations with park reservation passes, 6 month ADRs, 2 month FP's, increasing lines, crappy dining options, even crappier transportation, etc....There's at least 2 more that are ready to come and drop a house payment on their first magical vacation. I used to scratch my head at this- where did all of these people come from? But the fact is, they still do. So they will never accept a guest retention problem exists until they also see a negative new guest rate.
Until people, en masse, start voting with their feet and visit the boy wizard instead, WDW will continue to squeeze the loyalty right out of us.
