We've stayed at both GCH and the DLH. Both had a cord that you plugged in to the computer, in the rooms. So I'm betting it's the same thing at the PPH.
But they do have a really nice "desk" area in the rooms that you can sit at. Not like hojo that had us trying to make the cord reach the bed. Which was not easy, as it was too short, and very uncomfortable (cord was between the two beds on a small night stand). Wish they would have had it set up on the table! Then I don't mind cords!
