It is amazing what you forget. Luckily, I did a blog and we can look back and recall the visit. It is a magical place, although I doubt we'll ever get back there.
If you get a chance, do go. At every turn it is beautiful and the people are warm and welcoming. It is NOT like the UK. Yes, the people speak English and lots of the birds in towns are English ones, but the wild places are different with wild tree ferns and many trees quite different. 4 million people instead of more than 60 million helps!
