I would decline the invitation.
I am fortunate to know, personally or through friends, several famous entrepreneurs, more than just their name and their business success.
None of these people attract me in the least. One example: I nominated this entrepreneur for a prestigious award. My nomination propelled him into a select group of finalists. Not only did he fail to appear at the award announcement, but he never even thanked me for nominating him and for the publicity he gained through being a finalist.
I much prefer the company of people who selflessly serve others without promoting themselves.
