We are also going Feb. 2 - 9th and hoping a code will come out. I have a package booked as well. The last 2 years in a row we booked a package, the discount that was released for packages was the free upgrade to park hoppers, waterparks and more, and there was a SLIGHT room rate reduction.
IF Disney does release a discount code for our timeframe, I'd look for it around October - November.
Again, it will depend on what the discount is - it may or may not apply to what you have booked like the op stated.
Lets keep our fingers crossed though that it's a good one!!!
