What is the best strategy around creating and selling adventure travel packages to entrepreneurs?

I'm close friends with several speaker and published authors. We've been mulling the idea of creating a getaway adventure for entrepreneurs. It would include zip lines, horseback riding, hiking, seafood cuisine, microbreweries and wineries while also incorporating several hours of learning and working on their businesses. The idea is for a small group ie 10-12 business owners. What is the best way to sell this kind of package? What kind of price point should we consider?
