I am planning a trip in Cambridge
I am happy to help, can you please give me some information on what you would like me to search for?
I'm looking for a place to stay in Cambridge in the expensive range with a 0 star rating that includes free parking.
I'm sorry, I'm not seeing any options for an expensive place to stay with a 0 rating and free parking. Should I look for something else?
How about one with a 4-star rating?
There are 2 hotels that meet your needs, one in the west and one in the city centre. Do you have a preference on where you'd like to stay?
The one in the west will be fine. I'll need the address, postcode, and if they have free internet. 
Sure their address kingfisher way, Hinchinbrook Business Park, Huntingdon and the postcode is pe296fl and they do have free wifi.
Great, thanks! Also, will you please find me a train that goes to Ely, leaving on Friday?
We have 10 trains that leave every two hours starting at 5:50, any time preferences?
I need to leave after 10:30. 
TR0767 leaves at11:50 on Friday morning, arriving 12:07. Price is 4.40 pounds. Would you like me to book a seat?
Yes please. Book it fror friday, 2 peopl. I'll need a reference number as well please.
I will complete that booking for you now.
Okay. Great. Can I have the reference number please?
