I need a room. 
I would love to help! Which part of town would you like?
I am looking for a guesthouse to stay at in the moderate price range that includes free parking.
There are 12 guest houses that fit that criteria. Is there an area of the city you would like to stay in?
No specifics on area.
You might enjoy the Acorn guest house. It's rated 4 stars, and offers free wifi as well as free parking.
Could I book it for 7 people for 4 nights starting Friday? 
OK, I have your party in the Acorn Guest House. Your reference number is: V4CGYNW3. Anything else I can do for you?
Thank you. Yes, I need a train leaving Cambridge to go to Stevenage. 
I have 2,828 trains available, what day would you like the train?
I'd like to leave on tuesday after 21:15 and arrive at stevenage.
I have train TR7822 that leaves Cambridge at 21:21 and gets to stevenage at 22:10, resulting in a 49 minute train ride. It costs 12.80 pounds.
That sounds good.  That was all I needed.  Thank you.  
Should I make reservations?
Yes, please I need the train I.D also
How many train tickets do you need?
Booking is not necessary, I just need the train ID
Ok, is there anything else that I can assist with?
thats it, just the train i.d
The train ID is TR7822 as mentioned previously. Anything else I can do for you?
Nah, that's pretty much it. Thanks.
Great, have a great day!
