With cross-selling of multiple hotels you can lead guests to your partner hotels if you don't have any availability in your hotel.
How can I activate cross-selling?
Go to http://login.hoteliers.com and go to the tab White Label Plus. Next, click on Whitelabel+ settings on the left of the screen and navigate to Cross sell hotels (comma seperated). Fill in the Hotel ID's of your partner hotels to offer those hotels when there is no availability left in your hotel. All hotels have their unique ID number. If you don't know you hotel ID number, you can navigate to hotel data > Hotel Main info and find on top you Hotel ID.
