Ellie Anne does your husband want to go too his brother's funeral? Have you asked him as it's so far from where you live. If he does want you both to go is their a family member who could take you both so neither of you have to drive.
My worry is you say both of you aren't good drivers anymore and 9 hours is a long journey especially as you aren't well. Both of you will be stressed driving and I worry about your safety.
My brother was a HGV driver but he wouldn't drive 9 hours in one go now. He would go half way and stop overnight and then continue his journey.
Also if the funeral is in the morning unless you set out at stupid o'clock it will mean more than one night out.
Did your brother in law have a family and would they want you to travel all that way?
I know it's a lot of questions but these are the things that I would think about.
Soops kitchen, a place of reflection, refuge and at times revelry.

). I'm glad your husband has felt well enough to do his model plane. I remember my dad liking those Airfix ones.
