Hi, You can do the reservation through the hotel/guesthouse/hostel where you stay in Mandalay. It is much easier than doing it on your own. The show is on every night so you can select a convenient day for you.

The show begins at 8:30 and lasts for over an hour. Go online to get reservations in advance since your one night in Mandalay might coincide with a big tour group. You would not want to arrive to find all the tickets sold. Look online for the web address for Myanmar Marionettes. choose "performance" information for time and "reservations" to get your ticket Lots more to read on the website. The theatre opens at least 30 minutes before the performance so arrive at 8 to get the best seats. Mandalay Hill has great views. Take a taxi as far as possible then walk up the stairs to the top level.

Pop into the theatre earlier in the day as you could come across a large group they are very helpful hope you enjoy the show
