For that matter, I wouldn't hesitate taking beginners all the way to Iceberg Lake. It's just a walk, (except for the weather, altitude and snow issues) especially in winter when people can go over the snow instead of climbing the Ebersbacher Ledges.
If your plan is to do the MR in the summer, the winter is a great time to go up and take a peak a ledges and to ascertain their location. That was one of the purposes of our trip up there.
My guess is getting to LBSL is a lot easier and safer in the winter than in the summer
