My husband and I did this tour on September 25th ... its a late review but we have only just returned from our holiday.
We were picked up on time from our B n B accommodation with no issues and at our table at the venue there was only 9 of us. So we had spare room to move.
We all thought dinner and the show were ok, I'd say 7 out of 10.
However we were hoping to get some photos with the performers. When I asked our guide, he just answered, oh its too cold and once the show its over they go straight home. Thought that was a lame excuse and pretty piss poor.
Also on the glow worm tour, the guide said if you have previously been to the Waitomo glow worm caves, you'll find this part boring.... and yes he was correct.
