There's a thread about member services's hours that conveniently forces people to say that they plan primarily during the week. There are questions about the website.
There are questions about the frequency of your visits: how many trips this year, how many nights, how many on points, what percentage on points, is that more or less than before you joined...
THere are questions about how important various bennies are: golf, dining discounts, ticket discounts, as well as how often you use them. (BTW, I thought the design was interesting in that there's no way to indicate the cross benefit of DDE membership. I marked that dining discounts were very important, yet I had to admit I hadn't actually used a true DVC discount at all.)
There are questions about various exchanges, how often you plan to use them in the next three years.
There are two places for plain old commentary. I flat out said that I'd sell if we at any time received lesser benefits than other resort guests received.
If anybody else answered, please chime in about what I've forgotten.
