In my experience, they have frowned on my asking for "free upgrades" when booking the teacher's rate. I have a SPG , but not enough points accumulated. My last trip at the Swan for example I had a $129 standard booked, when I asked about the possiblity of getting a balcony room upgrade I was told "No - they are all booked" (The receptionist seemed very bothered by my request)
When I got to the room, I actually called the hotel to try to book a balcony room I was told were all sold-out, and not to my surprise was told that that they WERE available. I wanted to go back down and tell the lady who checked me in off, but I figured I got what I paid for so I should be happy with that. The one time I booked a standard room with "AP rate" I received a comp upgrade no problem. So , I'd be curious to know if anyone has received an upgrade with "teacher's rate".
