Platinum
I recently stayed at the Venetian for the $109 rate. I checked in at the regular registration desk because I was in a hurry. I did not present my PC Platinum number at this time. Later, I stopped at the PC registration desk and they said it was for Ambassador but they would recognize my Platinum status. I was offered a room upgrade but declined since my king room was already a big step up from where I usually stay. I also got free newspapers at the news stand, free wifi and a 2pm checkout. Nothing else was offered. It's a good thing I did not read this thread before my stay because I probably would never have mentioned my Platinum status. I received no PC points for the stay.
