U: I'm looking for a train that leaves on Saturday and arrives by 10.30

S: Where are you traveling to and from?

U: I am going to cambridge from birmingham new street.

S: There are 5 trains available, may I book one for you that leaves at 7:40 and arrives at 10:23?

U: What is the train ID?

S: The train ID is TR8259.

U: Yes, that train sounds good. Please book it for me. Could you also find me a hotel with a moderate price that offers internet?

S: Before we start on the hotel, did you need tickets for the train?

U: No thank you, I was just pre-planning a route.

S: There are 17 hotels listed. What part of town would you like to stay in?

U: The north part of town please, preferably in a guesthouse.

S: Cambridge has 8 moderately priced guesthouses in the north.  I would suggest Acorn Guest House, with a star rating of 4.  Would you like me to book it?

U: Before I book it, can you tell me if the beds are comfortable?
S: A couple guests were treated to comfortable sleep at the Acorn Guest House, but most felt the bed were uncomfortable and extremely poor quality.
