A very personal review: I am not into mass show, but because in Siem Reap and saw this advertised, I gave it a try. Let's say that it will be the only and last time I will book this kind of event.
Even though I clearly indicated the pick up location, I had to call the organiser to finally get our tuk-tuk from the hotel. Use WhatsApp to call the organiser, best way to get rid of them. And then, among the tour operator guests and roughly 300 people, you will try to get some food as it looks like people have been starving for 3 days to enjoy the included buffet.
The show is 60-minute long, and I have to be fair that it is good but really on a routine such that it really turns out to be the tourist attraction of the time. However, nothing like the pictures posted to advertise this show, don't get too excited.
The way back to the hotel was OK, but this was after having to prove again and again that I had really booked and paid for our dinner too!
So let's sum up: organisation was poor, show was average, and the audience was... 'tick the box, eat as much as possible, jump on the stage as soon as the music stopped to have their pictures taken with the dancers' kind.
I don't often write such a review, but I won't recommend this considering experience/price, particularly when there are other low-budget shows which are far worth in Siem Reap.
But again, truly a personal opinion, not everybody is made of the same mould.
