Since most of Melbourne was still shut by the time my husband and I arrived, and we still can't check-in our room at the YHA, our first stop was the Crown Casino after leaving our luggage at the hostel. Crown is open 24 hours a day, 7 days a week except on Christmas, Good Friday and Anzac Day. We walked around and had a small breakfast there before heading back to our hostel to check-in.
At nightfall, we decided to go back to the casino for more exploring and to try out one of the cafes. It was perfect timing because when we arrived by the grounds, there was fireballs show (gas bridages), which apparently shows every hour, on the hour, from Monday to Friday (9pm to midnight) and on Saturday and Sunday (8pm to midnight), unless weather does not permit it. It was a great show! There were lots of stuff to see and to try in the complex, even if you're not gamblers (like us). However, we didn't really have enough time to experience it all. But, it's definitely a good place to check out if you're in town.
