On the AP site it says "From now until April 30, take advantage of up to 40% off regular
Disneyland® Resort Hotel rates and enjoy a little extra something in your pocket while you and your family play at Disneyland® Park, Disney's California Adventure® Park and the Downtown Disney® District."
I don't see an actual name of the promo, and they don't prompt you to ask for a certain rate...
As an idea...PPH is showing as 179, 169, and a couple nights of 149 all through April with only the last three days as not available.
DLH is 209 from the 1st to the 18th, then a week at 189, and 2 days at 159.
(plus taxes, plus resort fee, plus tax on the resort fee...subject to change blah blah blah, LOL)
