No you buy the tickets from a booth

You have to go to the desk to get tickets, there are 3 price levels but i would advise to get to the most expensive as a much better view.

However i would not bother with the translation headphones as you can workout what is happening as long as you have seen something of Hanoi.

No, I just bought them a few hours before the show. I apologize for not getting back to you sooner. Show was great.

We bought them at the door about an hour before and there will still plenty of seats left.

I too bought the ticket at the door.

I bought tickets at the door 15 minutes before the show

Can be bought on the spot.

We bought them at the theatre just prior to the performance

Mine were delivered to my hotel along with complimentary photographs, so cool..

You can go to the theatre and print right there. They have screens so you can do it yourself.
