WDW officially announced that free in-room wireless will begin today in the following resorts:

Disney’s Animal Kingdom Lodge
Disney’s Beach Club Resort
Disney’s BoardWalk Resort
Disney’s Contemporary Resort
Disney’s Coronado Springs Resort
Disney’s Grand Floridian Resort & Spa
Disney’s Old Key West Resort
Disney’s Polynesian Resort
Disney’s Saratoga Springs Resort & Spa
Disney’s Wilderness Lodge Resort

No official word on whether it will appear at other resorts, but my understanding is that it will reach the moderate resorts eventually, as well. Possibly by the end of the year.
