Disney has invested a huge sum of money in the NextGen project that is going to introduce quite a few new trip planning technologies across the entire Walt Disney World Resort. The latest product to receive an update is a brand new version of the official DisneyWorld.com website
The site has been completely rewritten and no longer uses Flash technology. This makes it much more iPad friendly. The site is also more focused on providing information and creating trip itineraries. The new website also features a dedicated "My Disney Experience" section, that portion will allow visitors to manage all of their Fastpass+, ride reservations, dining, accommodations and PhotoPass.
The website is currently not available to all users, as it is being rolled out gradually. It appears to be random, so keep trying if you want to see the new site before his full launch.
I've included some screenshots of the site below:
