Congratulations, Paul. All the best with that.
Re: your question, you could use something like:
"The world's newest premier golf destination", or, the longer version, "The world's newest premier golf destination, in one of the world's finest resort locations", or, longer still, "The world's newest premier golf destination, in one of the world's finest resort locations, designed by one of America's greatest golfers -- The Links at Cabos San Lucas".
Unfortunately, I don't think I've actually MADE UP any of those phrases myself -- they all seem too eerily familiar; but honestly, so does "world class golf site"
