I need to get to cambridge on friday.
There are 1414 trains heading to cambridge, what is your starting destination?
I need a train that departs from stevenage on Friday. It should arrive in Cambridge by 11:00
Certainly, the train that arrives right before 11 is TR2860 arrives by 10:43. Shall I book it, if so how many riders will there be?
What is the departure and travel time please?
It departs at 9:54 and arrives at 10:43. That gives you about 15 minutes to spare. Is that alright?
Yes. I also need a place to stay please. 
i have 33 hotels, what area would you like to stay in?
Area doesn't matter, but I would like something moderate priced that includes wifi.
That leave us with 17 choices. Do you care whether it's a normal hotel or a guesthouse?
I would like it to be a guesthouse please.
The acorn guest house fits your criteria as well as includes free parking - would you like me to book for you?
Yes I will need that for 2 people for 5 nights for Friday please. I also need the reference number. 
Booking was successful for your stay at acorn guest house starting Friday. Your reference number is : 8IGOI38R.  Is any further assistance needed?
That's all I needed. Thank you!
Fantastic! Have a lovely visit! Goodbye!
