If, after clicking the "Add BookNow app to Facebook" button you are not able to add the widget, the problem may be caused by one of the reasons below:
Reason 1: You MUST be an Admin of the Facebook fan page for your property in order to add the BookNow widget. If you are not an Admin, you must ask the Page Admin to perform these steps.
Reason 2: If you receive a blank page instead of the page shown below when setting up BookNow, please delete all cookies from your browser. If you don't know how to delete cookies in your browser, please consult your browser's documentation:
Reason 3: Facebook now only allows pages with more than 2,000 likes to install Tabs, which is needed for BookNow to be shown on your page. An error message will be shown if you have fewer likes.
