Well the way I read page 26 is that Hotwire and Priceline combined provided the Lowest Rates for Hotel Tests - 83% of the time. Providing for an average savings of 24% (Hotwire) to 16% (Priceline.)
Quikbook had another 13% of the Lowest Rates.
Why would anyone use Orbitz, Travelocity or Expedia to book a hotel?
