Need help with coupon code affiliate

I have received affiliate approval from a couple of brands, such as hotels.com and Unice, but they do not permit bidding on branded terms like "Hotels coupon code". As an alternative, I am considering creating a dedicated coupon page and running Facebook ads targeting the specific brand. For example, I would create a coupon page for hotels and then include "hotels.com" in the interest targeting for the ads. Do you think this tactic will be effective, or could it potentially be a waste of time?
