To which I point out: GC had told us that when we got the answer, a numeric code, we should come back to their room to tell them. But, in hindsight, I don't think all the players heard that. And the players that did hear it weren't following the solving action.
E.g., me. I wasn't following the solving action. Oh man, that room had an air conditioner, but it was not equal to the task. Oh man. Anyhow.
