I hope they're using something other than WEP for their encryption.  They
mention they use 128-bit encryption, but they didn't say what they were
using.  WEP is broken.  And SSL is vulnerable to man in the middle attacks.
An attacker could have a field day just sitting in their parking lot.

> Murshid S. Khan, director of telecommunications and 
> technology support at Walt Disney World , talked about the 
> theme park's use of wireless technology during Stamford, 
> Conn.-based Gartner Inc.'s Wireless LAN Summit here today. 
> According to Khan, Disney World, which includes the famed 
> Magic Kingdom and Epcot Center, is part of an interconnected 
> world that includes as many as 200 wireless access points 
> hidden throughout the park. The access points are used to 
> facilitate the flow of information and data behind the scenes.
> Khan described how the technology use has evolved, as well as 
> where he believes Burbank, Calif.-based The Walt Disney Co. 
> plans to go with wireless LANs in the future. His comments 
> came on the last day of the three-day Gartner event.
> The decision to provide 802.11b coverage for most of the 
> amusement park grew in response to visitors' complaints about 
> being unable to use credit cards to buy food, beverages and 
> Disney World merchandise, Khan said.
> "We were running a food and wine festival and a lot of people 
> had complained in the past that they couldn't use credit 
> cards [to pay for items]," Khan said. "When people go to the 
> park, they want to use credit cards. So we changed that."
> With a wireless LAN in place, employees can now accept credit 
> card purchases and complete authorizations quickly, he said, 
> speeding up transactions and making it easier for visitors to 
> buy food and merchandise. The technology also allows 
> employees to be mobile, meaning they can boost revenue by 
> bringing merchandise and food to people who may be stuck in 
> line waiting for rides.
> "They're not static; they're mobile," Khan said. "And 
> mobility has enhanced revenue generation."
> The technology is also used for "guest tracking" on Disney 
> cruises, especially during stops when travelers disembark for 
> island excursions. As each person arrives on board one of the 
> company's cruise ships, Khan said, he is given a card. As 
> passengers leave and return to the ship, they are required to 
> swipe the cards in a device that tracks who has come and gone.
> "That tells us who's on board," Khan said. "Let's say 200 
> people have gone onto an island. If we see that 200 people 
> have not come back, we know how many people are missing."
> Although the company's goal is to provide a wireless 
> workplace for its employees throughout the park, there have 
> been challenges in implementing the technology, Khan said. 
> "Bandwidth is an issue in some areas. Integration [with wired 
> networks and applications] is an issue. Seamless roaming is 
> an issue," he said.
> But the biggest hurdle is security -- ensuring that tens of 
> thousands of credit card numbers are sufficiently protected 
> during multiple transactions to prevent theft and working 
> constantly to keep "sniffers" from illegally connecting.
> Khan said Disney uses 128-bit encryption and other means of 
> detecting possible intrusions with software. Though he 
> declined to be more specific about how the company protects 
> its network, Khan stressed that Disney is constantly looking 
> to beef up security, especially as the network grows and is 
> used for more services.
> During a question-and-answer session after he spoke, however, 
> Khan acknowledged that wireless LANs are still a new 
> technology that may not be right for all businesses.
> "This is an emerging technology," he said. "It's going to 
> take a while before everyone feels comfortable with it. For 
> small business groups, you can [implement] it. But for larger 
> Fortune 500 companies, I'm not sure the rate of return is 
> there. You have to be comfortable before you jump in."
> "If someone is asking me about applying this for office 
> automation, I'm not sure I would do that at this point," Khan said.
> And while he said Disney plans a gradual move to a faster 
> 802.11a network in the years ahead, he said the company has 
> no plans to deploy Bluetooth technology. Bluetooth is 
> wireless technology with a shorter range that is designed 
> primarily for the personal-area network among devices such as 
> telephones, handhelds, laptops, printers or fax machines. By 
> contrast, 802.11b networks are seen as being better-suited 
> for workgroups or other places where wireless connections can 
> be spread apart.
> Asked whether Disney might ever offer some of its bandwidth 
> to park visitors, Khan said no. In addition to bandwidth 
> concerns, he said, there are also more practical worries.
> "We need you to come to the park and enjoy the park," he 
> said. "If we start opening Internet cafes, you won't do 
> that."
