For one thing, the museum is not easy to find. We went to Kassel with German friends who visit Kassel fairly often, and they had difficulty finding it. It's a non descript, gray building, and unless you're looking carefully, you will miss it. We drove past it twice before seeing the sign! This place is obviously not well regarded as a tourist attraction!
Once we found it, we discovered that the top two floors were closed for renovations, which were, incidentally, the floors I was most interested in. The saving grace here, was they only charged half the admission fee as we could only see half the exhibits.
The bottom floor was almost entirely devoted to Frau Holle and nothing was in English. Fortunatley we had Germans with us who could translate. The second floor was dedicated to the brothers love of music and instruments.
The gift shop had very little of interest.
Until the top floors are opened again, I would give this place a miss.
