Sorry for your loss but no clue here. Could be a one trip wonder type thing....

FWIW - I can somewhat relate and I hope my being frank is acceptable. My dad is in a nice wooden box on a shelf in my closet as my frugal mother want's to take him down with her. No sense digging him up again so everyone was happy with the cost savings when I said he can hang out with me until that last hole is dug.

Personally, I'd like to be sprinkled someplace nice only because whoever volunteered would get a meaningful trip out of it. When my mom passes, I may hold a little back and plant a tree in my yard in his honor. He died rather unexpectedly so/but/and knowing him, I expect whatever I decided would be fine by him.
