A product recommended for a brand will be visible by another brand, except that this offer would not appear at the top of the list.
The recommended offer for a brand appears at the top of the list of search results (product catalogue) and displays the brand logo on the product sheet.
In the case of a multi-brands hotel, the logo which will be displayed will be the one of logged account hotel brand, even in the product is multi-brands.
Example: a multi-brands hotel Novotel, Mercure and Ibis Styles is been created with the brand Ibis Styles. Consequently, hotel users will only see the logo of Ibis Styles for recommended products, but it doesn't mean the product is only recommended for Ibis Styles.
