As far as I know, I am the poster who first brought this issue up months ago, took some flack and skepticism (understandable), etc. And yes, my un derstanding is that the union contract (of which, servers, like the DIS, make up about .3% of all workers and have no power) - the union contract can revert to the old contract through a loophole if Disney decides they are negatively affected by the new 2008 DDP (financially). I don't know the details of this, only that it does apply to servers gratuity and such. I cannot 100% confirm this, but am simply passing info received from a reliable source. Still, take with a grain of salt.
I am happy that people are expressing their opinions to Disney. Do not be discouraged, every call and email helps. Disney, like any company, wants to hear the thoughts of its guests and get better insight into the decision-making its loyal consumers make.
Just so we put the DDP in perspective, here is its history over the last 5 years - after 9/11/2001, Disney and all tourism suffered hard. Remember, air travel and tourism has only really recovered in the last 2-3 years - there were some very very lean years in 2002 and 2003. How did Disney lure the guests back, and get them to stay in the Disney resorts instead of off-site? The DDP (which became very popular with repeat guests and got great word of mouth).
Central Florida was devastated by 3 hurricanes in late summer/fall of 2004. Hurricane season also falls in a very very dead time of year for Disney historically, late August and September. School has started so family vacation decline, yet it is still very hot and humid in Florida - thus, guests historically stay away in September. So, Disney offered resort discounts and the free DDP (called the "hurricane plan" in 2005 by the way). Disney figured it was better to get guest revenue through hotel bookings and ticket sales (as well as selling merchandise and all the extras that guests spend at Disney World) by giving away free food.
The key here is that SYNERGY was involved. Disney didn't care if it "lost" money in its food and beverage department, because the profits from other areas far exceeded these losses.
Indeed, it seems Disney resort profits (disney lodging) have been incredible the last few years; the hote's' occupancy levels are at very high levels year round (even with price increases at these very resorts). It is undeniable that DDP has contributed significantly to guests' decision to book on property as opposed to off-site.
Disney is indeed now testing the waters - it wants to make food and beverage more profitable while keeping its others line of business (ticket sales, resort profits, merchandise revenues, etc etc) the same or increased also. This year, in addition to the hidden increase in the DDP out-of-pocket costs, you will see restaurant prices increase again, though very modestly (a dollar here and there for buffets or entrees, for example). You will also see prices at popular buffets (character meals, Ohana, etc) increase a few bucks at peak times, like Christmas, spring break/Easter, etc.
Let me assure you that Disney will get a very quick idea of how this new plan is going over with consumers. January and February are also historical slow periods for Disney tourism. Rest assured that if DDP, and more importantly, resort reservations drop off substantially from previous years, Disney will take notice. As DIsney hears guests calling and writing that they will stay off-site because of the changes in DDP, and indeed Disney revenues at resorts suffer, they will put two and two together.
I am not advocating that you simply tell Disney this - be honest. Let Disney know how DDP changes will affect your future visits (if it affects them at all). Many on here have expressed that they will not purchase DDP, and some say they will save money by staying off-site, because DDP was the main reason to stay at Disney. Others will still purchase the plan and stay on-site. That is fine.
The bottom line is the bottom line - if Disney starts losing money, they will make changes. If this happens, they will make the appropriate changes ONLY if they stay well-informed from their loyal guests.
