I am a 40yr old South African guy who has been living in Sydney (Australia) for 11 years. My wife is Canadian and we have a 9 month old daughter Viv. I have been running an online marketing consultancy called CleverClicks for 5 years. I travel a lot to the US for training and conferences. Staying with local people is the way to go.
I've used AirBnB to stay in Nashville, Philly, Seattle, Singapore... all be good experiences
