I'm mostly writing a review of the membership options. If you're going to go more than twice a year, it's worth getting a membership. You get discounts at the shops and restaurants, access to the member's lounge, free entry (with a shorter line) to the special exhibitions, and if you like you can get a membership to bring a friend with you for about $120... or you can split it with a friend and pay $60 a piece. Brilliant.
