dznynerd,
You can stay at the Polynesian on contract rates (if they have availability)--they won't be as good as staying at the Contemp. at SOG rates.
Currently, guests of SOG are being housed in the North Wing of the Contemp while the contruction goes on. SOG guests are being charged what they would have paid at SOG (based on rank) plus the 11% room tax. If you stay on SOG property, there is no room tax--so the rates are 11% higher...but still a fabulous rate!
If you elect to stay at the Polynesain and they have availability at contract rates--you can make a ressie through SOG. I have discovered that these rates vary from season to season and I estimate that they are about what you would get for an AP discount.
Hope that helps!
