From my time at the agency, it seemed like they start with smaller groups and work their way up from there. AP rates typically came out first, followed usually by Florida resident, Disney Visa then general public.As DisneyJoe and Bolt have said, certain rates for Cast members and TA's are fairly constant however the rooms allocated to each might change, I have definitely seen that happen. I have heard that Priceline, Hotwire etc purchase rooms at a wholesale rate and then re-sell them at the rate that is seen online, however that was not from an official source so I cant swear for that one. I dont know if there is an "official" order on discounts and if there is, it is not something that I would know. Sorry Len!! Marie
This order of course could change whenever they felt like it, but it appears to be the shall we say normal progression.
PIN codes were very hard to track as we only saw them when a client told us they had one or we checked ourselves while booking and they never appeared to come in waves like you would expect if they released a bunch at once. My gut tells me that they were most likely not part of the normal promotion release and were part of a much finer tuned system to fill up very small holes in occupancy.
