Sue, you will love Lord Howe.
Spent 6 days there 18 months ago. Cost me a bundle for the wife and myself, but best thing I have ever done.
Only down side, I didn't find out till the day I was leaving that there were windsurfers on the island and that Tim had windsurfers for hire. Would have made the holiday perfect, but that will have to wait till next time when I win Lotto, then I will be staying for 6 months.
By the way don't hire a bike named Paul. My wife hated it, him.
Problem was she is vertically challenged and didn't really have a choice.

Mind you if you want shopping centres, mobile phones, cars etc, don't go. But somehow I have the impression that's not you.
Never been to all those other windsurfing Mecca's, but now I've been spoilt I'm not inclined.
I have added my amateur attempt at a panorama just to tempt you.
