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: I'm on a budget so I need to verify that the rooms are a good value?
S: Several of the past guests found that the hotel rooms were rather large and spacious, one customer felt the rooms could have been a bit bigger.
