A: Where can I get a tour of the city? B: We can arrange a tour for you right here at our concierge desk. A: How much is the tour? B: It depends on what kind of tour you want. A: I hear you have a half-day bus tour. B: We do, and it is $25 per person. A: Can I get off the bus and explore on my own? B: You can only do that if you take the all-day bus tour. A: Is that more money? B: It doubles the price. A: That's highway robbery, but book me anyway. B: That will be $50 then.
