Thank you very much for your answers!
I had found the page on myswissalps for First-Grosse Scheidegg but no information about Schilt and difficulty and I thought that maybe someone had done the Marmot Trail and knew something about it.
I searched for a map and found this www.grindelwaldbus.ch/ en/hiking-and-exursions . So the hike would be 17, intstead of 6. And I see that it's just a half an hour longer, so I think this is ok for kids, and not too much extra work so they all blame me and grumble in case it's not so interesting and full of marmots. It's an extra 100m level difference and looking on the map it seems that it's a short distance where you gain this elevation, but I think this would be ok for them.
