Cheese and chocolate factories

My family plans to visit Switzerland in June. I will be travelling from zermett to geneva and plan to travel through Broc to see the chocolate factory. My questions are
1) after arriving at Broc Fabrique how do I reach the chocolate factory?
2) how do I include a visit to the cheese factory? Mode of travel between cheese and chocolate factories.
3) how do I mange my luggage?
4) are these visits and the one to Gruyers castle included in the Swiss pass?

Hi swisstraveller,

I think what you're after is the Chocolate Train excursion. Please see this and this topic as well.

Thanks.
I would not like to spend so much on the Chocolate train. Can I not do it on my own?
