Apparently Wilderness has WiFi for a fee
Does Fort Wilderness have Internet access?
Yes. Like the other resorts, Disney offers wireless Internet at three hot spots and broadband cable at the sites and cabins. The three WIFI spots at Fort Wilderness are Reception Outpost, Meadows, and Crockett's Tavern. Cost is $4.99 for the first 60 minutes or $9.95 for 24 contiguous hours. Technical Support is available 24 hours a day, 7 days a week, by calling the vendor, Smart City, at their help desk: 407-938-HELP. Both the Cabins and Preferred campsites can also rent a cable modem kit to have high speed Internet access. A Local Area Network (LAN) cable is required. The necessary modem kit is rented at the Front Desk in the Outpost. A $125 refundable deposit is required and the kits should be reserved in advance or will most likely not be available. Cost is $9.95 for 24 contiguous hours. Dial-up access is also available at the Reception Outpost.( from http://http://allears.net/acc/faq_fw.htm )
