The last two times my family and I have stayed at the Contemporary the internet access on our in room comuters has been 100% free and since no one said otherwise, I assume when we check-in there tomorrow it once again will be free. To back up my last comment others who have recently stayed there said it was free and no one has reported that there is now a cost.
However I was told that it would not be free forever so who knows when and if there will be a cost. I will say I was told that information last year and it's still free.
