$50 of apps is more than all the WDW apps I've found cost combined!
Search "WDW" and "Disney" in the app store and you'll find most of them. Here's what I have:
Maps of DCA, DL, EPCOT, MK, AK, DHS and DTD [all created by UPinPoint.com]
Notescast apps: WDW Guide and WDW Secrets
WDW Dining
WDW Times
What 2 Ride [WDWMagic's first iPhone/iPod app]
and an icon that opens m.disneyworld.go.com in Safari
