			This is an example of a booking URL.

			Please note that the only field that is mandatory is the prop id. Everything else is optional.
	        Here's an explanation of the parameters used:

			propertyID=1135 – this defines the property that will be pulled on the booking page. For Sheraton Delfina Santa Monica Hotel this will always be 1135. This is a mandatory field
			roomOccupancyTotal=1 – this defines the total room occupancy (includes adults + kids) and they may use a javascript to calculate that using a dynamic form
			departureDate=2010-12-10 – this is the departure date. This should pull from the form
			arrivalDate=2010-12-09 – this is the arrival date. This should pull from the form
			lengthOfStay=1 – this is calculated by javascript automatically and it can be optional.
			numberOfRooms=1 – this defines the number of room (it can only be up to 9 rooms). This info should pull from the form
			numberOfAdults=1 – this is defines the number of adults and pulls from form used on the website
			language=en_US – this is the language variable. This defines in what language the booking page will appear. (other values are: fr_FR for French, es_ES for Spanish, de_DE for German, it_IT for Italian, ja_JP for Japanese and zh_CN for Chinese)
			ES=Custom_Tracking_Code – this can be anything they want as long as it includes the brand id and the prop id. Here’s an example they can use: ES= sheratondelfina.com_SI_1135
