24 hours

next weekend i am going away to Sydney. It is literally a flying visit - I'm just there for the weekend. 
So my question is - what would you do in Sydney if you were only there for 24 hours? 

Last year when I went it rained torrentially for 3 whole days but I still managed to see the opera house + spent  the whole at the MCA (which was sooooo amazing!) 

So far I have little planned apart from going to the finder keepers market (the whole reason for the trip) but I would love some suggestions! I'm staying just near Hyde Park which I am excited about because it was one of my favourite places to visit the last time. So,please leave a comment and help me plan my trip! 

p.s: happy mothers day to all the sweet mummy's out there xx
