I am not certain I understand your question. I looked at the link to the Museum website and it does say "Closed Now" but that is because it is not now between 9 and 5 in FRANKFURT. Otherwise I did not see anything that makes me think they are closed for renovations or any other issue. Good luck and I hope you get to go!

I am sorry, I have no clue, I am afraid you will have to email the facility for this level of specific detail.

We specifically asked for an English speaking tour in August 2018. There was a set time for this on a specific day(s). I cannot imagine going through this tour in a language that you are NOT fluent in, even if you speak a few words and phrases. Understand you are COMPLETELY in the dark and you will need to rely on the guide's verbal directions...and at least in our English tour , they did not give the directions is English and German. It is really not so much whether the guides are fluent as much as what language the people in your tour group are speaking.

Dear Lynne, I realy don't know. I am only a visitor, as you are. You should ask directly them. Goran
