I've had okay luck with the Wyndham site, and I've rarely found a deal that beats the Allied Business Network (free for anyone) corporate code, except for an opaque booking (Hotwire, Priceline Express Deal, etc.) or possibly a non-refundable rate. That code only works directly through Wyndham, and it still earns Wyndham points. I'd rather do that than pay the same or more on hotels.com, especially since typically to get a discount on hotels.com you lose the free night after every 10 nights.
