Upgrades at Disney World
The folks at Disney will be investing almost $1 billion to equip their parks and guests with new technology that includes bracelets for visitors that can act as their ticket into the park and a way to purchase items easily once there, just like a credit card (kinda sounds like what most cruises do now already - probably even the Disney one).
MyMagic+ will also allow would-be/soon-to-be guests the opportunity to choose up to three FastPass tickets on rides before they even leave for the park.
This is starting at Disney World - with about 30 million visitors annually - and I'm guessing, if successful, will expand from there.
