Não posso ajudá-lo ! Fui de táxi ao museu.

i am not sure but french was availble

a little more than 1 dollar

We used the audio guide and it took me about 2 hours and my friend closer to 3. The time will also depend on if you want to read every thing. You may not be interested in all aspects covered. It well worth the time and effort.

Dentro do museu há elevadores... Eu entrei pela rua principal e para acessar a entrada, tive que subir uma escada. Não sei dizer se há um acesso para cadeiras de roda. No interior é muito fácil o acesso .

Yes it does. Make sure for the little extra you do the audio as it is well worth listening to the stories.

It was 30 000 dong/$1.30 US

I think it is 8am to 5pm. I recommend the morning if walking in August.

30,000VND each.
