I saw on facebook last week that the secret word is back again! On December 2nd the facebook page was updated to say:

"Just when you started to really miss it... the Secret Social Password is back! Today through March 4th, just say “Warm Woolen Mittens” at check-in and receive a special surprise from the hotel. Don’t worry, you don’t need to whisper it – we love to hear you use it loud and proud!"

Anyone have any luck using it yet? Also, has anyone ever had luck calling ahead of time to see what the hotel will surprise you with?
