This is something Disney pro's are sure to appreciate... A $10/day per ticket option allowing park visitors to basically collect Fastpass reservations digitally. In other words, you don't have to run from attraction to attraction to add them to your ticket. Sweet!
Yahoo explains further:
Maxpass will allow mobile booking of the passes through the Disneyland app. According to Disney's site, it will allow guests to "maximize their experience by providing unlimited downloads of their high-resolution PhotoPass images and by enabling the convenience of mobile booking and redemption of Disney Fastpass return times - all by using the Disneyland App."
