Attendance up 2.2%, I don't think that is "soaring" at all, especially not since this is the first gain in 2 years. Merchandise up 12+%, that indeed is good, but I would bet the vast majority of that gain is WWoHP. Does WDW need to worry about this? Absolutely not, I actually believe their profits ended up higher than expected.
WWoHP will be great for Uni., but will doubtfully have any negative impacts on WDW. In fact WDW might actually get visitors who otherwise wouldn't have gone to any of their parks but went to Orlando specifically to see WWoHP and also decided to hit WDW. I seriously doubt WWoHP will have any negative impacts on WDW's financial gains. Now, hopefully it will encourage them to add some new rides, fix some existing problems, do more than the FLE, etc., but realistically Uni. does not, and probably will not ever, truly compete with WDW.
