I am planning a trip in Cambridge.
sure, do you need some information?
I need to book a train from Cambridge to Leicester, leaving after 20:00 on Sunday. 
There are 4 options leaving after 20:00, by what time do you want to arrive in leicester?
It doesn't matter when I arrive, but I need to make a booking for 5 people. And I definitely need a reference number for the booking.
Booking was successful, the total fee is 151.19 GBP payable at the station, your reference number is EM5AYOET. Will that be all?
Actually, I could use some help finding something fun to do in the north. 
There are several swimmingpools as well as a park and a boat attraction in the north. do any of these appeal to you?
Can you give me the address for the park?
The address is milton country park, milton, cb46az. Will that be all?
no that will be all thank you
Do you need anything else?
No thank you.
Okay, have a great day!
