Hi there. I am looking for a train out of Cambridge. 
What is your desired destination?
My desired destination is Norwich.
There are many trains for Norwich, do you have a specific date and time you'd like to leave?
Friday after 18:15. I will need 4 tickets. Please send me a reference number too.
Booking was successful, the total fee is 70.4 GBP payable at the station .
Reference number is : CLBJ6WLI. Anything else?
I need a hotel that is moderately priced. I do not want a guesthouse.
There are three. Ashley Hotel and Lovell Lodge in the north are 2 stars and Cityroomz hotel in the centre is 0 stars. Do you have a preference?
Is there anything with 3 stars?
There is not. Would you be willing to try a different price range?
Yeah, lets try expensive places.
The gonville hotel meets your needs! Would you like me to book that for you?
Yes please for the same group of people on tuesday.
How many days would you like to stay?
I'd like to stay for 3 nights, please.
Alright, got you booked. Your reference number is: AL3YQFJ8. Anything else I can do for you today?
Nope that is all I need today. I appreciate your time! Thank you.
You're welcome. Have a great day!
