No but they do have written translations in several languages which I though was nice.

No, unfortunately we do not have any audio guides. Only live guides, and only in English at this time.

The guide only provided information in English. Unfortunately I don't think they offer tours with other languages.

I've been twice and the tour is in English only, provided by very entertaining guides.

In writing I believe

I think there were, but not entirely sure
