curious.. i'm thinking about climbing Mt Fuji this summer (early July) with my 11 year old son. I understand it's not off-season but this seemed like best Mt Fuji hiking thread out there. I have decent experience hiking (did Kilimanjaro a few months ago), my son is good but but would be his biggest hike. A few questions:

-how realistic is a hike with a 10 year-old?
-Do I need to decide ahead of time between sleeping on the mountain or not? Ideally would prefer doing up and down, starting early but i understand that given his age, I might want to decide later on to stay for the night.
-Any other tips related to this?
