I'm sure that it is possible for DVC to implement a system that would allow us to see our points online. They could also implement a system that would allow us to check availability online. And if they really wanted to, they could probably implement a system that would allow us to make reservations online.
However, it takes money and time to implement these types of systems. In the long run it comes down to what is the best solution for members. It might turn out that an online system is the cheapest cost wise for the members. Then again it could turn out to be more expensive. Would we as members be willing to pay extra for such a system? Having been involved in developing some customer self-service applications, I know that he cost for developing these types of systems easily runs into the millions of dollars. Also, there is the cost for additional computer systems that need to be purchased, the extra system management of those systems, plus they would most likely still need to keep a significant portion of the current Member Services staff to handle those people who do not want to do everything online or who are in a place where they do not have access to a computer.
Personally, I'm all in favor of such a system. However, I wouldn't want to pay substantially higher dues for such a system. So, like most things in business, it comes down to the cost/benefit analysis. Is the benefit worth the cost? Without DVC doing some initial planning of this system, it is impossible to know how much it would impact our dues. I would hope that this type of system would eventually reduce the costs, but it really is hard to say until the research is done.
