Where is the woman getting information about the Opera House tour? [originaltext

W: Hello.
M: Hi, Erica? Tim here.
W: Oh, hi, Tim. Helen said you might ring. You’re going to Australia, right? And you wanted some information about tours of the Sydney Opera House?
M: That’s right.
W: I got a printout from the Opera House website. Let me just get it...right. Opera House Tour. OK. It says: "This is our most popular tour..." blah blah. "Visitors are given a fascinating account of the history and architecture of the building. " You see the concert hall, the opera theatre, you hear about the current programme, et cetera. What else do you need to know?
M: Does it say how often the tour goes?
W: Let me see...it’s a one-hour tour and, yes, "it leaves every half hour between 9 a. m. and to 5 p. m.
M: Right, every half hour. So they’re pretty frequent. And does it say how much the tour costs?
W: I think so, yes, at the bottom here—adults...23 dollars. But there’re some concessionary rates for, um, senior citizens, and also full-time students, plus kids under 16. So remember to take your student card and you’ll only have to pay 16 dollars. Oh, it also says something here about the backstage tour, "An opportunity to explore behind the scenes at the Opera House. Appear on the stage and see where the orchestra plays. " You also get the chance to chat with some of the technical staff and maybe even some performers, if you are lucky...
M: Sounds really great, but how long does that one take?
W: Um, that’s two hours, so twice as long as the first one. But there’ s an early start—it goes at 7 a. m.
M: How much is that?
W: Let me see... 150 dollars. Well, anyway, if you’re interested, you’d try and book well in advance if you can. I think the tours get quite booked up.
M: OK.
W: There’ s a number you can call for bookings or if you want some information. Have you get a pen handy?
M: Yeah. Fire away.
W: OK. It’s 92507250. That’s Sydney, obviously. Did you get that?
M: Got it. That’s brilliant. Erica. Thanks a lot.
