We did the combo tour of a guided walk at 4.30pm, then the Maori greeting, dancing and hangi in the evening. I was going to go for 3 stars but the geyser put it up to 4. The tour, conducted round the attractions (geysers, mud, weaving hut, carving school and kiwi enclosure) was given by Mel, who is a excellent guide and pleasure to spend 90 minutes with, and we did gain some insight into Maori culture. The geysers, bubbling mud and hot steps are great, and definitely worth seeing by themselves on a general admission ticket without doing any of the other stuff (if you're pushed for time in Rotorua just do this). The evening entertainment was polished but very touristy and not really my cup of tea. The hangi feast after is nice food but like eating in a canteen and your experience will entirely depend on how entertaining the other folk at your table are. Things pick up after dinner when you get a wee train down to see the geyser again at night and sit on the hot steps. This is a nice end to the evening. I did like the fact that the staff we interacted with are local and related, and clearly have a love for the place. So in summary, go for the geyser, if you have the time and money do the other stuff but you won't be blown away, or come out with a detailed knowledge of Maori culture.
