Getting ready for Sydney

2 weeks 'til my trip to Sydney and I am traveling alone this time, not that I didn't try to get some friends to join me for mardi gras but aparently no one has any money or can't take time off.
I am actually quite excited about going down under on my own, used to travel a lot on my own when I was younger and one of those trips resulted in a 19 year relationship. Not expecting that this time, but I'm sure I'll make lots of new friends.
I am however panicing a bit , Sydney is so body orientated - so no more food and double the gym time
