We are going to be in Tauranga and our port time has been modified to arrive at 4:30AM and leave at 4:30 PM. We have a 7 hour shore excursion, (Rotorua- Te Puia, Geysers, Culture and Kiwis) booked with Zeelandier Tours that returns us to the ship at 3:30. We are concerned that this is cutting it too close and does not allow for any unforeseen delays with traffic, etc. Zeelandier assure us that this timeframe is fine and they will get us to the next port (Bay of Islands) if necessary but this alternative does not make us comfortable. Does anyone have any opinions if this is cutting it too close?
