Internet Access
Dial-Up Access with a Laptop
All of Disney's resorts have data ports on the phones. If you want to access the Internet from your hotel room using the data port, you'll need a dial-up account. Remember that they'll charge you .75 each time you connect, even to a local or toll-free number.
Off-site, you'll find that pretty much any decent hotel in the area will have data ports on the phones. If you want to access the Internet from your hotel room, you'll need a dial-up account. Hotels vary widely on how much (if anything) is charged for local and toll-free calls, so be sure to check before using dial-up access.
High-Speed Access with a Laptop
All of Disney's convention hotels and Home-Away-From-Home/Disney Vacation Club resorts (Beach Club Villas, Boardwalk Villas, Contemporary, Coronado Springs, Grand Floridian, Old Key West, Saratoga Springs, Villas at Wilderness Lodge and Yacht Club) have wired high-speed Internet in all guest rooms. There is a charge of $9.95 per 24 hour period.
Disney now offers Wi-Fi (high speed wireless Internet access) in the public areas of its convention hotels. You will need a Wi-Fi enabled laptop computer or PDA to access the Internet from designated areas of each resort. Your credit card is billed through an on-screen Internet connection. Use of this service requires a wireless interface card (WIC), available for purchase in the resort's business center. It costs $9.95 for a 24-hour period.
Locations for Disney's Wi-Fi access:
Contemporary - Main Lobby, Convention Center Hallway, Feature Pool
Coronado Springs - Main Lobby, Convention Center Hallway, Feature Pool, Francisco's
