while we have only been 7x, and i feel like we deserve something, it is what it is. i email WDW upon returning from each trip. I compliment on the good and mention what we thought was not so good along with suggestions for improvements.
they have alway called back. during one of those conversations, i asked about how to get discounts, etc...I was told it is run by a seperate company and done at random, having no ties to guests travel patterns, frequency or cost. Based on the fact that you have been so many times for so long, i would say that is proof of what they told me.
playing devil's advocate, i think of it this way. Disney is the best at what they do, hand's down. On the other hand, no one is perfect, not even Disney. I'm sure their database and statistics on guests, employee's, operating expenses, etc..is mindboggling. We have to remember, they are a For Profit business. Plain and simple, they have to make a profit. In the end, they have to try and find ways to keep things fiscally attractive for a broad spectrum of the population, yet still be profitable. I am sure that is a fine line that they walk every minute of every day. Like they say, it's tough being number one and staying number one. Because Disney is so good at what they do and at taking care of their guests, i think that we expect perfection and forget to give any room for WDW to breathe or be human. This is not to excuse any faux pas that WDW may be 'guilty' of, just a point of view.
my take on Disney is that $ for $, I haven't found anything that beats it for a vacation. every time i look at other places for trips, the costs come up similar or more expensive. I know that eventually we will do other destinations for our family vacations, especially as our DS's get older. For now, i just don't see any way that we can beat WDW in value. We have incredibly fun vacations that also take us away from the daily grind, phyiscally, mentally and emotionally. For us, that is a real vacation.
All I can say is that you are privelaged to have been to WDW so much and hopefully you don't lose sight of that. I understand if you feel like a comp is due, i certainly think you are overdue. However, i'm sure there are thousands of people, if not millions, who feel the same way.
In the end, I am grateful for what WDW does provide for the money. This has enabled us to have some incredible vacations during the past 7 yrs and hopefully for many more to come.
IMHO
That's my take on it, too. I'd love to see some studies, because I strongly suspect the average new visitor spends a lot more per person or per day than a frequent visitor. Honestly, as a local I spend as little as possible - the rare merhcandise item and limited food & drink. BUT, advertising to those new markets costs a lot more. Wish I could see some numbers!
When you are use to having an AP discount for all nights of your vacation, and then they suddenly cut out the weekends, it is a bit shocking. But I guess nothing in life is for sure. We went ahead and booked Pop Century. It's not really what I want, but since we are only there a couple of days before spending a week in a 2-bedroom villa I really don't have anything to be upset about. The kids love Pop, so they are excited. 
I am sooo jealous! We live in Indiana and its quite a trip for us to do disney every 2 or 3 years. We were so excited when the 4/3 deal came out because that meant we could actually afford to go this year
