It's not like you're there to relax, or anything: Carnival Cruise Lines has equipped its Carnival Valor ship (not boat, mind you) with Wi-Fi everywhere. They're claiming 100-percent coverage with their Cisco gear, including all rooms and public areas. The press release avoids mentioning costs, which is an odd oversight. Why not just be upfront? It's not like folks won't find out if they ask. On other Carnival ships, Wi-Fi access costs 75 cents per minute or as little as 55 cents per minute if you purchase a 100-minute prepaid card.
