I think it depends slightly on when you die, which I realise sounds odd!
If you die when still relatively spry and active, involved with local people and events, then more people are likely to come than if you live to a great age, in a nursing home or hospital say, when many friends and even family have already died.
How often do we hear someone has died and you think that has happened already, as you have seen or heard nothing of them for a long time?
As for direct cremations, yes, cheaper, less fuss and arrangements, but I wonder if later on remaining family might feel they missed out on a final goodbye?
Closure, an overused word nowadays, but maybe more relevant than you think.
