All travel sites that sell hotels online work together with GDS, suppliers and hotels directly to search for room inventory. Once the travel site sells a hotel, the site will try to get a confirmation for this hotel. Once confirmed or not, the customer is contacted with the result.
This means that booking a hotel on a travel website will not necessarily result in an instant answer. Only some hotels on a travel website can be confirmed instantly (which is normally marked as such on each site). As different travel websites work with different suppliers together, each site has different hotels that it can confirm instantly. Some examples of such online travel websites that sell hotel rooms are Expedia.
The comparison sites, such as Kayak.com, TripAdvisor and SideStep search the resellers site all at once to save time searching. None of these sites actually sell hotel rooms.
