At AKV Jan 1 to Jan 4, I called the internet help people and they suggested to sign in and then have the front desk remove the charges. I did need to check-out, no folio on door, and did have a $5 game room charge and two nights of internet charges. The CM quickly removed the charges, saying there had been some miscommunication with members, and that free internet would begin in Spring 2008.
The internet help people do not have the same info as the hotel people. However they did specify that if I were renting my points, the renters would pay the internet charges. Only DVC members are eligible for the free internet.
