Worth trying with a safety pilot while under the hood is to fly your
airplane all the way down a time or two. Full ILS to mins, keep the
localizer centered, maintain rate of decent. Sometime when everything
is stacked against you you may have to do something like that in real
life. It's a confidence builder knowing you can get down in near
zero/zero.

Mooneys with their low wings tell the pilot when they are a few feet
agl. I don't know how a Cessna would feel though.
