I usually am able to get a discount, at the very least, my AAA discount. Also, I've used some excellent pin codes. Right now I'm already booked using AAA for the end of Aug., (I've gotten no Pin code for those dates) but am constantly checking for any way to get a discount.
I will respectfully disagree with the statement that there is always a discount available. There frequently is, especially lately, but not always. I am very WDW discount-aware, and have taken a trip when there was absolutely, positively no discount available for the resort category we wanted for the dates we wanted.
It was an unusual trip for us in that it was pretty last minute. We hadn't been planning a trip, but the opportunity to fit the trip into our schedule came up just two months ahead of time. This was absolutely the only time we could travel that year, and at that point there was not even a AAA rate room available much less a code or special offer. I even had my AAA agent checking for me, as well as checking by myself. So I either had to pay rack rate and get over it, and enjoy a great vacation, or I could refuse to go at full price and miss going to WDW for the year.
We chose to go enjoy ourselves, paying full rack rate for POFQ, and it was worth it.
What I absolutely will not do, though, is pay rack rate for a deluxe. That, I cannot justify. But that is just me.
