Last year,my husband and I decided to visit New Zealand．We wanted to tour the count,but we both don't like long coach journeys．Our travel agent (旅行社)advised a 13-day coach(长途客车)trip．It was a good price，so we booked it and our plane tickets to Christchurch．We made a good choice．The coach journeys passed quickly and our driver told us about each place．We learned a lot from him．
We flew from London to Christchurch and had a free day there before the coach trip started．We weren't at all▲,so we walked around the city from morning to night．It has good museums，many restaurants and lovely shops．
The most unforgettable place we visited on the trip was Queenstown．We had three days there．but it wasn't enough．We did lots of things there,from sailing to climbing．At the end of each day,we felt we had no energy(精力)at all．But the next morning it seemed(似乎)that everything was fresh again!
All the hotels we lived in were good．My favourite one was the Puka Park Lodge．It was on a hill above a beach and there were trees everywhere．We woke up and listened to the birds singing．Now,when we're eating breakfast at home and we hear the noise of the traffic,we think of those beautiful mornings in New Zealand !
