I think you should visit sites like miceage.com or mouseplanet.com and read the Club 33 threads in the Disneyland forum on each site. The membership benefits have changed dramatically which might have led to a wait list opening that you got.
Let's be clear though, this type of membership does not have a clear ROI and if you are even thinking about the value of the various benefits versus the cost, you have already made the decision. I suspect most people who are members do so like buying a really expensive $100k priced car, many of the benefits are not tangible.
