If you are thinking about booking the houseboat, do it! :)
We had a lovely three night stay, and were lucky enough to arrive and leave the boat in glorious sunshine. We enjoyed the welcome drinks on the top deck, and I had a dip off the back of the boat with the ducks - such fun. The bedding and towels are of good quality, and the boat is kitted out with absolutely everything you might need.
A once in a lifetime experience for us - we are glad we did it but it got a bit of a pain having to have short showers to conserve water. Would still recommend though!
We visited Waikeiri Terraces whilst we were in Taupo on recommendation from Maureen and had a lovely time. Top tip: go early to avoid the crowds!
