Happened to my wife and I once. I complained to them on the phone, but they were unsympathetic. I told them they should stop selling Early Bird after the A's are used up and the fact that they allowed people to pay them for a B number was a sham and misrepresentation.
It works from the ship, even if she is docked in CC. However, it doesn't work in CC or near the ship. You have to be on the ship. (I tried it from the dock just off the ship and couldn't get a signal). MAYBE you could work on the ramp? Didn't try it there. I was maybe 15 yards away from the bow?
