In years past as long as your vacation started by the last day that a code was available they would give you the discount for the entire trip. Now they only give you the discount up to the last day of the code. We have always gotten AP discounts for mid May. This year is my daughters first year of kindergarten and her last day of school is May 21st, so when the AP rates came out I thought great, we can leave that afternoon still arrive on the 21st and get the discount. Wrong, I would only get the discount for 1 night the 21st then the rest of my stay would be rack rate. Needless to say I'm not going to change my dates for 1 nights discount.
