That sounds like a great trip! Let's compare and contrast with my Prestwick trip:
My trip to Prestwick was all within one day: I left my flat at 0515 and got back at 2330 on the same day.
My trip was over two countries, Mark stayed in England.
Mark's trip included 18 holes of golf, a first-class lunch, and a cricket match, while mine only included 27 holes of golf and two trips to Burger King. Mark definitely got a lot more done within the trip.
Mark's trip involved a couple different modes of transportation, and he came and went from different rail stations. I walked and trained everywhere (Euston is a 10-minute hike from my flat).
New Zealand is supposed to be a classy heathland layout, but I doubt it beats Prestwick for quality.
The company on Mark's trip was top-notch (even you Boon), whereas I did the whole trip by myself.
Overall, the two are pretty comparable. Mark, it sounds like a great day's adventure--makes me miss my time over there once again.
