This is all I could find:
Grand California and
Disneyland Hotel:
Super value season is 1/6-2/13 and 9/1-26
Value season: 2/24-3/6, 4/13-6/19, 11/7-11/24, 11/30-12/4, 12/7-12/11, 12/14-12/18 **I can't find confirmation of the "value rates" for the DLH and GC, so these are guesses. I'm not sure of the October rates but think they are probably value season. The Super value rates are from the 2008 brochure.
Paradise Pier:
Super value season 1/6-2/13 and 9/1-11/6.
Value season: 2/24-3/6, 4/13-6-19, 11/7-11/24, 11/30-12/4, 12/7-12/11, 12/14-12/18
It looks like they may have followed WDW in making the President Day week part of the regular or peak season.
