If you have a "silly" off-line form on your hotel website without the current occupancy status and room rates, you are diverting visitors to the accommodation catalogs. They would like to stay with you, but they didn't get a chance. So they might try booking your hotel in the catalog, which takes a substantial part of your profit in the fees. And worse, they will see there your closest competitors, nicely arranged, with their action offers. Why???
You can't lose anything. You can only get more profitable orders from your web.
