I think it has been said many times before but if your visit is only for a few weeks and you're only planning on doing a small amount of hours, it's probably just better to rent a plane with an instructor; I'm sure you will increase your skill level and have a relaxed and enjoyable time. A couple years ago I booked a holiday with
Flyinn New Zealand | The Mountain Flying Adventure of a Lifetime, South Island and had one of the best times of my life.
