M: Hello, welcome to Golden Times Travel Agency. Can I help you?
W: I’d like some information about trips to Seattle.
M: Yes, of course. What would you like to know?
W: Well, how do your tour groups travel?
M: We go to Seattle by plane. After arriving in Seattle, we travel by bus.
W: And how many people are there in a group?
M: Well, there are at least 20, with, of course, a driver, and a guide who will look after you.
W: How long does it take to go there and come back?
M: Well, it depends. We have five-day trips in spring and autumn, ten-day trips in summer.
W: I’m interested in the five-day trips next spring. Can you give me some ideas of how much that’ll cost?
M: It will cost something like 800 dollars per person.
W: I see. Thank you.
