It went through this time with Thomas. He mentioned that all persons making reservation ustilizing a special group rate should be using the "group code". This made sense since the previous time I had called they asked me for the code, which I didn't have. But Thomas was nice enough to check further and found it .

The Group Code for this group rate is: C/SUPCO
The special rates for the standard rooms are $49.00 up to Feb 2nd. For Feb 3rd and 4th it is $89.00. The group rate is not available after the 4th.
