A train depart from Cambridge and arrive by 19:00 
What is your destination? And what day are you hoping to travel?
I need to leave on Thursday and am heading to Bishops Stortford.
There are 5 trains available what time would you like to leave by?
I'd like to leave before 14:00
Okay, TR0927 leaves at 13:29 and arrives at 14:07. Shall I book you a seat?
No, I'll look it up later and do it myself. But could you tell me if there are any 4 star places to stay in the city centre?
There are two, a cheap guest house, and an expensive hotel. Any preference?
Which ever one has free parking and wifi.
They both have free parking and wifi. How about the alexander bed and breakfast? It's on the cheaper side, 4 stars, and really quite lovely.
Sounds great. Can you please book that for me for Tuesday for 2 people, 2 nights please?
I was able to successfully book you, your reference number is D53TP7EU., can I assist with anything else?
Nope, that's all I need today. Thanks!
You're welcome. Have a great day!
