We've stayed at VWL several times over the past year, and the rooms were never dirty, nor did the furnishings, bedding, etc. feel spent. Used, yes...think of the traffic these rooms get. Spent, no.
Just like non-virtual world rumors, one Disboarder's reported experience with a room victimized by shoddy housekeeping quickly becomes a generalization for the whole resort. You could probably at any point in time on the Disboards find a room report on every DVC property that would leave you quaking.
If you visit a lot, there will likely be an occasion when something about a room is awry (like the rolled up dirty diaper we found behind a curtain in an AKV room). Happily, that's been the exception rather than the rule for us. Now, if multiple people have the same experience over time, then that's more valid evidence to me of an overall trend of a property falling into disrepair.
An isolated set of messy rooms could be the result of a cast member who is just not cut out to be a mousekeeper (and who hopefully will quickly be identified as such and re-cast).
