Best trip we ever went on was to New Zealand. We used Robert Panzer of Tailored Travel. He picks you up at the airport and there is not another worry. He will not take more than 4 people in his van and inquires before the trip to see what your interests are.
You stay at wonderful B & B's, he plans all excursions, makes all dinner reservations (great restaurants) and all is pre-paid so you don't have to worry about how much you will spend. He knows his country well and has lots of local contacts to make the trip very interesting. We can't rate him high enough!!
