Q: M: Hello, Milton Hotel Reservations. How may I assist you? W: Hi, I'm calling to make some changes to an existing reservation. M: Certainly. Do you have the reservation number? W: Sure, it's 219. M: That's a reservation for Sally Menkel. Is that right? W: Yes, that's right. I'd like to change the check-in date from September 15 to September 16. M: Certainly. I can make that change for you. Is that the only change? W: No, the check-out date will also change from the 23rd to the 24th. M: No problem. We have you arriving on the 16th of September and leaving the 24th of September - altogether, eight nights. Will there be anything else? W: Yes. Instead of a courtyard room, I'd like a room with a view, preferably on an upper floor. M: I can certainly change that for you, but there will be a change in the room rate. The new rate is $199 per night, instead of the original $179. W: That's OK. These are all the changes. Thank you very much. M: You're welcome. Have a nice day!
