The museum is staffed by volunteers and was closed until the 4th January. Try them next week, they should be up and running again. Well worth a visit.

And I found the email address on their home page, scroll to the very bottom. TA won't let me post it. But like the person above said, they were probably on their holidays if you tried this past week.

You can catch the train to Kew Station from Waterloo. It's about 2 minutes walk from there. You could also go to Kew Gardens station and catch the 65 bus from there. That will take longer.

Hi Nonglak, we have a small replica street with recreated shop fronts from a bygone era, to provide a setting for our street and barell organs. There are a couple of photos of the street gallery (also known as Lamb’s Passage) on the website. Unfortunately due to lack of space, it is not a real street and the shops are not fully fitted out. I hope this answers your query.

They can listen to the presentation + will probably be invited to interact with the instruments. Very nice experience.
