Hyatt joins the end of the long parade of hotels providing broadband access: Their service will be powered by T-Mobile HotSpot, and installed in their over 200 hotels and resorts by 2005.
Meanwhile, historic Mackinac Island's Grand Hotel, while away from the fray, has full Wi-Fi: The site of many movies and a constant stream of business conferences, the the $300-starting-rate hotel includes Wi-Fi service throughout. Cell phones don't work well on the automobile-free resort, but at least you can check your stock quotes through an underwater cable connection.
Wall Street Journal coverage (paid sub. req.) of the T-Mobile/Hyatt deal quoted Pyramid Research saying that 6,000 hotels worldwide would have Wi-Fi service this year; 14,000 by the end of next year. Former Pyramid analyst John Yunker, now with Byte Level Research, told me via email that domestically, U.S. hotels would number 2,100 for Wi-Fi only (including just lobby coverage) by the end of 2004, but wired and Wi-Fi together would number 5,100.
