Sidestepping the thread a bit...
Redweek generally has listings for Hawaii, at least Maui, that are $500 to $1000 under VC. If someone contacts VC for a week and they don't have it, they will shop Redweek to fill it...and mark it up to their market rate, at least enough to cover their $500/10% commission. With exception of late rentals, I generally do better or net the same than if I used Redweek; and VC customer service is great. That said, if you have week that can be differentiated from all the others, Redweek is probably better as you can list the differences, e.g., guaranteed floor.
I tend to track VC, Redweek and VRBO to see what asking is for a given week and it obviously varies by remaining time before check-in.
What never ceases to amaze me are the folks that rent on VRBO, via VC. They pay the full VC rate, plus the VRBO service charge, when they could just go straight to VC. With all the fees the cost can easily be $1000 more than my net on VC or Redweek pricing. And don't get me started on having to pay the 15% Hawaii tax hit out of the net, if playing by the rules.
