We have an endowment policy which will pay out enough on the first death to tidy us both away. You pay £50 a month for 10 years and it pays out a minimum of £10k. Once paid up it sits accruing interest until the first death. Thanksgiving service is organised and family are aware so there is no need to think any further.
OTH a cousin has a prepaid plan into which she pays £35 per month until the day she dies. She has paid it for over 10 years so far and is very fit and healthy so will obviously pay lots more over the next few years. She is happy that it is sorted so clearly you pays your money and takes your choice.
It is entirely up to you! 
He never gives up being stupid.
