From the Chicago Tribune:
The nearly 20 resort hotels within the Walt Disney World complex in Florida have announced a new no-hassle baggage system for both inbound and outbound travel that will begin May 5. And, for 18 months, you won't even have to pay for it.
Here's how it works. You can arrange your accommodations at a Disney World hotel the way you usually do—through a travel agency, online, as part of a package or whatever—and you must fly to/from Orlando International Airport on American, Continental, Delta/Song or United/Ted.
Then, 10 days or more before departure, reserve your "Disney's Magical Express" transfer in Orlando. Disney will send you special tags to apply to your baggage.
When you check in your bags at your home airport, that's the last time you see or handle them until they arrive at your hotel room. On arrival at Orlando, you go right past the baggage claim and head for the Disney shuttle to your hotel. The "Magical Express" folks will claim your bags and deliver them to your hotel.
On departure, you can get a boarding pass and check your bags for the flight in the hotel lobby—whenever you leave your room, but at least three hours before departure time. You don't have to see or handle them again until you arrive back at your home airport.
The new service is especially helpful on your return if you have an 11 a.m. checkout time and an evening flight home.
I bolded that one bit because that's the first time I noticed it--does that mean that you don't have to check-in at the airport? How cool!
