From what I saw on TV during an interview with the widow, her DH bought THREE crypt spaces from someone years ago. It may have been Hugh Hefner. The DH was put in the one above Marilyn Monroe, leaving two empty ones for the widow and their family. She wants to pay off her house (not cheap) and leave it to her kids free and clear, plus whatever else she can. She doesn't care what spot she gets as her final resting place.

She plans to auction off the spot above MM, and relocate her DH one space over to one of the two other spots she owns. She'll someday take the remaining space for herself.
Actually, I thought she was pretty enterprising and practical. If you have 3 spots and you only need two, why not sell the one that is potentially worth a fortune and have a bit of money for yourself and maybe even have some left to leave for your kids? I'm sure her DH doesn't care if he's moved a few feet.
