I need a train leaving Cambridge on Sunday.
We have quite a few options available to you, where are you heading to?
I need to arrive by 21:30 and go to London Liverpool street.
TR9732 departs Cambridge at 19:59 and arrives London Liverpool Street by 21:27. Would you like for me to book that?
Yes, for six people, please. I will need a reference number, as well.
I have completed the booking. The total fee is 79.67 GBP and your reference number is 58YNZ8EQ.
I also need a place to stay.  I would like a hotel with a 3 star rating and free parking.
There are 2 expensive hotels and 3 moderate price guesthouses meeting your needs. Does the area matter to you? Or the type of lodging?
I'm just looking for now. Can you recommend a hotel?
Okay the gonville hotel looks good, it's in the city centre. Would you like a booking?
I want to confirm with you that the gonville does not need to include internet.
The Gonville does include the internet.  Is that alright?

Shall I book you a room then?
