I booked the tour based on the really good reviews on tripadvisor. When the "bus" picked me up from my hotel, I was a little concerned as it was more of a big van (at least by American standards).
However, Nigel quickly put me at ease with his great conversation and ability to get everyone on the tour involved. The small size of the vehicle (relative to the big buses that other companies use) was actually really good for the day long trip as it made it more intimate and I got to interact with the dozen or so other guests. For someone traveling alone, this was a great option, and I cannot praise Nigel enough. He is a fantastic guide, cool guy to talk to, and he makes some good barbecue on the boat.
In addition to spending lots of time at Milford Sound, we stopped at a couple of other places along the road, such as Te Ananu, the Chasm, and Mirror Lakes.More
