I believe Disney would be smart to continue to offer perks. It shows appreciation for being a DVC member. I also believe that they should sharpen their skills at customer service and housekeeping. Saying "welcome home" is not enough. I would like to feel confident that my room will be ready when it should be and be in "working order". It should be a rare occasion that there is something wrong with a room. On that rare occasion when you need to speak to someone at the front desk, they should be professional and able to correct the problem.
My current impression of Disney is that they are not as successful as they used to be with their customer service reputation. It is intangible but it is what they built their business on. As that continues to erode, the perks won't be enough to satisfy people.
On our last trip over the summer, we had to go to the front desk for at least three days because of continuing problems with our door lock, magic bands, credit card issues,etc. etc. I never did get the chance to tell them we were missing a light bulb in one of the lamps. There were just too many other problems with our room and trip.
Perks might be an "extra" but we should at the very least get good customer service and housekeeping.
