I am planning a trip in Cambridge.
Okay, I can help you with that. Where are you heading in from?
I am actually looking for places to go. Specifically, I would like to find a park.
There are some lovely parks in Cambridge, and most are free. Do you have a preference for what area of town the park is in?
In the south, I will also need the postcode of the park.
I'd recommend wandlebury country park, their postcode is cb223ae. Will that be all?
I'm going to need a train too, is that something you can help me do?
Yes. I need more information about your trip first though.
what do you want to know?
Where will you be going?
to cambridge on sunday from london kings cross, I need 7 tickets and the reference number
Do you have a departure time or arrival time that you'd like to narrow the results down with?
I just need it to arrive before 20:45
TR1688 leaves at 13:17 and arrives 14:08. Is that acceptable?
Is there any other trains?
TR1681 is probably the best one for you. It arrives at 20:08.
Great, thanks! Will you please book 7 tickets, and send me the reference number?
You're all set. Your total is 132.16 GBP. You can pay that at the station. Your Reference number is : GNNG4MNQ . Can I assist you with anything else?
Nope, that's everything for today thank you. Have a great day!
Thanks, have a nice time in Cambridge. Bye.
