My guess is: he'll just do it. However, though he's not exactly a rock star, he IS to those who would use a Supercharger. He wont make it without the word getting out. He simply wont. He's doesn't seem like the type of guy that would use his kids as props. So I'm guessing he just wants to do it and enjoy the vacation time with his family. If he makes it clear that it's an event, and he wants company I'm sure I'd stop in and say hello. If not, I absolutely will not involve myself in any way and will encourage others to do the same.
I agree with Chad. I'm not a hero worshiper, or a groupie by any means. However, I believe that Elon is a special human being that only comes along a few times in each generation. He's doing something very important. He'll need an ever increasing balance in his life. If this trip gives him that without customers being involved it's all good. If that's the way he calls it, I'll respect that 100%.
