Tom,
No it doesn't matter, I was letting y'all know for a frame of reference. For the most part I'm going to guess there will be a cart or two per group (it's not an easy walk, at minimum it is a moderate walk).
Mike,
we do pass the carts on the way to 10. it's more rugged on the back. so if you're feeling tired ... grab one at the turn.
Cheers
