HTTYD Arena Spectacular

[Delta Shout]

Though I'm usually a Lurker, I just can't contain my excitement...
I'M FLYING TO SYDNEY TOMORROW TO SEE THE HOW TO TRAIN YOUR DRAGON ARENA SPECTACULAR!

Here's the BG:
My brother is friends with one of the cast members (He apparently has a non-speaking part ATM, but when the spectacular tours worldwide he will take on the main character Hiccup) and he and another mutual friend got free tickets in to see the show.
On Sunday, he was raving at how fantastic it was, how he loved it even though he'd never seen the movie and how I should go see it when it comes to Perth.
I told him that it wasn't coming anywhere near WA, and how its playing only in Melbourne, Sydney and (I think) Brisbane. Then it was onto a world-wide tour, no no-one over here would ever get to see it.
He laughed; "Well you could always come over here."
So I said: "How would you feel about next week?"
I booked all the tickets the next day, and -voila!- off to Sydney.
(My bro even booked another ticket for himself to see it again - apparently it was that good)

I've taken a few days off to wander around the city as I've never been before.
I know I'm going to Taronga Zoo, but does anyone who has visited/lives in Sydney have any suggestions of what I should do or where I should go?
