hi, in your b2b advertising I would advise to use linkedin ads over google or facebook ads, since linkedin I trust will give you the closest reach to the decision maker, and will help you identify potential clients in hospitality industry.
on other hand what we do is we do storified marketing campaigns to help growing brands likes yours find & retain best of targeted audience. and thus in your case as well we shall design a core brand story which will be used to design rest entire marketing communications like ppc ad copies, landing page copies etc.
