If you make a reservation through our central reservation center or a Brand Web site, we will collect and store your name, address and other basic information about you for the purpose of reserving the hotel accommodations. If you make a hotel reservation directly with one of our Hotels, state law in many states requires the hotel operator to collect and retain your name, address, telephone number and other basic information solicited on the hotel registration card and make it available to law enforcement officers. Our hotel operators send this information, as well as e-mail address and transaction detail (what goods and services were charged on the hotel bill) to our enterprise data warehouse or other data storage facility for collection and storage (the "Data Warehouse"). In addition, we obtain personally identifiable information from third party sources that are obligated to comply with applicable privacy laws and append it to the information maintained in the Data Warehouse about you. Credit card numbers used for payment or guarantee are automatically encrypted in our Data Warehouse so that they cannot be easily accessed. We do not collect Social Security or driver's license numbers from Customers.
