You can't possibly think that the discount rates during VALUE season will be the same as the discount rates during PEAK season. Actually I did the math:
Pop/value season is $77 a night (ends Feb/Prez weekend). AP rate is $49, making it 36% off.
Pop/peak season is $109 a night (begins Prez weekend and runs until April 16th). AP rate is $74, making it 32% off.
I don't see that the discounts are too far apart.
I agree with Misit, this is why I only go to WDW during Value and Regular seasons when the rates are better.
I think when the next round of discounts comes out after April 16th (when the season changes from Peak to Regular), the rates will be better--probably $59 a night at Pop. Basically the percentages are about or near the same, it's just the price of the rack rates that changes.
