While I agree quality has gone down and prices have gone up I don't feel DDP is the cause. I don't believe Disney releases figures but in talking with Disney staff during visits they've long told me while DDP is popular, most diners are not using DDP. I believe the cause is the fact that demand far exceeds supply. A packed house every night, year round will cause quality to go down, prices to go up. They'll keep doing that until people vote with their wallet. I enjoy many of WDW's restaurants but I wouldn't classify most as being upscale. What I do enjoy is the unique dining experience many provide that I cannot get at home. The Disney immersion. Unfortunately some WDW restaurants have become too much like what I can find at home.
