Thanks to everyone for the great discussion thread and the different perspectives. I agree with some points and disagree with others.
First, we are avid Disney fans and bought with DVC because of Disney's level of customer service to everyone, regardless of which resort you stay. With that said, this has nothing to do with changing the level of customer service and everything to do with enhancing the level of customer service. Being a DVC member alone, in my opinion, deserves what I call the 3 P's - Priority, Perks and Privileges. The reason I mentioned the tiered system is that this is how thousands of other organizations address their frequent customers. It would be great, if the fact of being a DVC member alone, would grant you special viewings, priority seating and of course the benefit of fast pass privileges. To me, buying into Disney should bring certain privileges to the buyer, than what is offered to the typical guest. You have not changed your service expectations overall, just added benefit for those who "invest" into and frequent your business.
Now, with that said, I do believe Disney can be compared to the airlines or hotel chains. Just because I bought DVC points does not mean I will be spending my time at the parks, which is what Disney wants you to do. The biggest selling tool the sales folks use is that by locking your room rates now, you beat the inflated pricing for the same level of room 30 years from now. When asked "why would Disney do this", the sales people say - Disney wants you to come to the parks and eat and shop and spend money at Disney. Well, guess what, Universal is 20 minutes away and I can use my points on any RCI property. So, in my opinion, it is certainly to Disney's advantage to offer the
3-P's for DVC owners. And the way to do this is either classify all DVC members as eligible for the 3-P's or create a tiered system that allows the 3-P's to expand as you buy additional points.
Lastly, it may benefit everyone if I explain my definition of what should be covered under the 3-P's program. Please add anything you think I may have missed. In my opinion, a DVC member should have, under the 3-P's program, the following - preferred room locations and views, preferred dining reservations with preferred seating and times, preferred fireworks viewing and show seating, preferred parking at the parks if you choose to drive (since the busses are getting more and more crowded) and unlimited fast pass+ privileges during your entire stay. I know I probably missed something, so please add what you think is important.
Again, I appreciate all of the comments and look forward to more discussion.
