I'm looking for a train from london liverpool street.
I have many trains that leave from London Liverpool Street. When would you like to leave?
I would like to leave on Sunday to Cambridge and get there by 16:00 or before. 
There are 5 options on Sunday from london liverpool street to cambridge. Would Sunday early morning be better? You could arrive by 07:07. Or would you prefer later in the morning?
I would prefer later in the morning if possible.
The TR9835 train leaves at 11:39. Would you like me to book that for you?
Yes, please. I'll need to book for 6 people.
Alright, you're all booked, your reference number is A6PU52R6. Anything else I can get for you?
I'd like a place to stay in the east of the city.
There are 6 guesthouses and 1 hotel in the east of Cambridge, ranging from cheap to expensive.  Do you have a preference?
Are any of them moderately priced with free wifi included?
Yes. I would recommend the Carolina Bed and Breakfast. Would you like to go ahead and book a room?
Yes please, I'll need a reservation for the same 6 people for 2 nights starting on Sunday.
Your reservation has been made at the Carolina Bed and Breakfast for 2 nights, including 6 people, beginning on Sunday. Ref# LHN3BIBK. Is there anything else I can yelp you with?
That is all I needed for today. Thank You!
