Platinum Pass Guest discounts

Hi there... trying to plan a trip in the Fall and I called today asking about discounts. Apparently Platinum Pass holders can bring in a guest for 39.99, and Friday's for 29.99 (up to four on Fridays). Come Labor Day the guest rate will be 19.99 but she was not able to give any details after that date. Does anyone know if there will be bring a friend discounts for halloweeeknds, has this been offered in the past? I'd like to bring a few of my son's friends with us on a Sunday in Oct but only if it's discounted :)

They have not offered discounts like that during Halloweekends -- but they have offered the 10% off for guests at that time....still, there have never been 19.99 or 29.99 specials during Halloweekends...which (except for Friday nights which have limited ride availablility) are the busiest days of the year for CP
