U: Hello.  I need to catch a train leaving on Monday.  Can you help me find something?

S: Yeah sure but you need a departure/arrival city and time.

U: i am going to london liverpool street from cambridge and should arrive there by 12:45

S: TR5431 fits your criteria and will arrive at 01:27. Would you like me to book that for you?

U: Yes, could you book 3 tickets and provide the reference number please.

S: Reference number is : 4HWC0OMV. Do you need anything else?

U: I also need to find out some information about the lensfield hotel

S: Ah, yes, the Lensfield is a very nice hotel. It's on the south end of the city and is quite expensive, but they have free wifi. Would you like a room?

U: No, but can you provide their address. Oh, and do they have free parking?

S: Their address is 53-57 Lensfield Road and they do offer free parking

U: Excellent. That's all I need.

S: Is there anything else I can help you with?

U: Yes, do you happen to know if they have rooms that are quite more spacious than the others?
S: If you're in search of a large, spacious room, one will be disappointed by the tiny, cramped accommodations at the Lensfield Hotel.
