I just spoke to my wife so I can rest easy until they head home again.
I've never spent any time in those cities Jerry so I won't make any recommendations. In certain places, aussie people are great. I can understand, however, when some aussies go abroad they come across as obnoxious and or rude. Some of my favourite people are just like that. They are not close friends but I find them interesting people, never a dull moment in their life. Given my wife is from a different culture I am more aware of what gets misinterpreted/misunderstood or taken the wrong way and what is just plain rude to other people. It doesn't stop me from doing the same things occassionally but wouldn't life be boring if we were all the same.
