In general, hotel room pricing is influenced by a variety of reasons including time of year, type of room, location, room occupancy and competitive pressures. Because of these factors, hotel room pricing can be updated and changed on a very frequent basis. Without getting into the technical details of how search results are returned on the website, sometimes after the initial list of hotels are displayed, there could be a change in the price once you click on your chosen hotel to see the room type availability. The reasons why it changes can vary, but include out-of-date data, a price increase or decrease, change in room availability and more. This does not happen often, and please be assured that we strive to provide you the best deals out there and provide you with the best possible experience.
