The answer is simple, there is no way … to answer that question, because it is incorrectly phrased. The real question is how to get to the first position on Google “for a specific keyword”.
it is no major success to be ranked no. 1 for a keyword that contains just your hotel name and the destination. however it is a major success if your hotel is ranked no. 1 for a keyword “accommodation <your destination>”. The process to achieve that is called SEO (Search engine optimisation).
That particular example might be a little difficult to achieve but there is no need to guess which keywords are being used by your guests. Google has a free tool that will help you discover precisely that. It is called Google Keyword Planner.
