I agree. Guest expectations legitimately change over time.
When OKW opened, the villas had VHS players. Now they have DVD players. Blu-Ray players are probably next. And eventually they'll probably have high-speed "cloud" media connections when streaming replaces any sort of tapes of discs.
When OKW opened, the entrance security gate was only manned at night. In the post-9/11 world, it's manned 24 hours.
Most lodging chains, even many low-end chains, have upgraded their bedding over the past decade.
Disneyland in California (including DVC Grand Calif. Villas Resort) has participated in this trend. All WDW resorts -- DVC and all categories of regular WDW resorts -- need to participate too. Guests expect it.
These are examples of adapting to changes in reasonable expectations over time. It's part of what it means to stay competitive and to take care of guests.
On the other hand, there are plenty of unreasonable expectations in this thread too. For example, I wouldn't expect any discounts that primarily reduce revenue, rather than driving new business. And I wouldn't expect costly "perks" that raise dues.
