Hello, We'll be visiting Sydney next month and I am ready to purchase tickets for a performance of Madame Butterfly. However, the ticket options have me confused. Our options include Stalls A, B and C "Reserve", Loge B, C and D and Circle A, B and C. All of these options have the term "reserve" after them. These are the options within our budget. How does one know exactly what this means? I'm looking at the seating chart and it's really not much help: sydneyoperahouse.com/uploadedFiles/About_Us/… . I'm looking at the price point for Stalls B, Circle B or Loge B. Help? Thank you in advance!
