If you mean take the money or take the trip, that would be a tough one. I’d have to see if all the needs of my family were already provided for. If so...to space I’d go! It’s a (for most of us anyway) once-in-a-lifetime opportunity.

What if it was a decision about $10 Million cash-to-forfiet v. the LEO space trip, or the deal on the lunar trip valued at $50M?
They would be eBay big by then and could do it.
