I need a cheap four star room. 
There are 7 guesthouses and 1 hotel meeting your needs. Do you have an area preference?
No but I need it to include free parking.
All 8 have free parking. If you're looking for a guesthouse, might I suggest alexander bed and breakfast? 
Do all 8 places have the internet?
Yes, they sure do. Do you prefer a hotel, or a guesthouse?
Can you suggest one for me? I need the hotel type, phone number, and whether it has internet or not. 
Sure, the Allenbell is a guesthouse with free internet.  The phone number is 01223210353.  Can I be of further assistance?
I also need a train on saturday that departs from cambridge.
What is your destination?
I'm heading to Leicester.  I need to get there by 21:00.
We have 15 trains going to leicester from cambridge arriving by 21:00. Was there a certain time you wanted to leave at?
If I could get the train that arrives closest to 21:00 please.
I recommend train TR6034.  The cost is 30.24 pounds and it will get you there by 20:06.  Would you like me to book it for you?  
Yes that would be great if you could book train TR6034 for me. Thank you.
Booking for TR6034 was successful for one person.  Your total fee is 30.24 GBP payable at the station and your reference number is A1E9MYGC.
That is all I need, thank you. 
Thank you and have a great day.
