WebHotelier supports redirecting to any landing URL.
This parameter is not supposed to be used alone.
The Landing URL can be combined with a source parameter in order to track a booking source that sends the user to a website other than the booking engine (usually the hotel's official website). The booking engine sets a cookie (usually for 14-days) and immediately redirects the user to the landing URL.
If the user comes back to the engine to make a booking, it will be attributed to the original source.
WebHotelier attributes bookings to the last booking source a guest has used to visit the booking engine.
