I need to book a train for Monday.
Where are you departing from?
I would like to depart from Peterborough going to Cambridge. 
I have 38 trains that meet your criteria. Did you have a preferred departure time?
Ideally it should leave after 13:45.
TR9063 leaves at 13:48. Would you like to book it? The next departure is at 14:19. 
Possibly, what is the price, arrival time, and travel time for TR9063?
TR9063 arrives in Cambridge at 14:38. Total travel time is 50 minutes, and the fee is 16.50 GBP per ticket.
Ok, thanks for that information. I would also need assistance finding a hotel in the north part of town. 
There are 13 hotels in the north of town. Do you have a price range or star preference?
I would like to stay in an expensive hotel, I know that for sure. I am not too concerned about missing out on amenities such as free parking and WiFi.
The acorn guest house is a four star hotel.  Would you like to try that one?  
Is it expensive, though?
The acorn guest house is moderately priced, but there are two more inexpensive guesthouses available if you would prefer.
The acorn guest house will do nicely.  I would like to book 4 nights starting Monday accommodating 4 guests. I will need the reference number.
The booking is successful, reference number is Y2ATA7D2.
Thank you very much. I think that is everything I need then.
Glad I could help you today. Enjoy your stay in Cambridge!
