If the 2016 parties go up to $100, that'd be a HUGE increase...honestly, as consumers, we should not jump on these tickets if they get close to $100 - rather, we should wait and see if Disney is forced to discount (as they have done for the magic morning and evening events). I mean, they already raised prices about 10% from 2014 to 2015. And 10% in a period of 1% inflation is already a huge price jump for a NON-refundable ticket at a shortened park event. And for reference, Universal is charging $73/night for their 2016 Halloween event (and requiring a minimum 1 day park ticket purchase usable on a different day or pre-existing AP) - although Saturdays are not included.
For Disney price reference...
