I need to find a train that goes to stevenage and arrives by 17:30.
Will you be departing from cambridge?
Yes, I will be departing from Cambridge. I also need to leave on Tuesday.
Sure I have a train arriving at 14:10 on a Tuesday. Would you like to book a seat?
Yes please. May I have the departure time, train id, and price?
TR0743 is leaving cambridge at 13:21 and the cost is 12.80 pounds, how many tickets will you need?
I just need to know how long the travel time it. 
The travel time is 49 minutes. 
I would also like to find an expensive guesthouse. 
I don't have any guesthouses listed in that price range. Would you like something in the moderate price range possibly?
Sure check moderate for me.
Might I recommend the Acorn Guest House? It's a moderately priced, 4-star guesthouse in the north area. 
Sounds great, can you please book me for 5 people and 4 nights starting on friday?
Okay, I made you a reservation at the Acorn Guest House. Check in is Friday for a party of 5 and your reference is CGDK1YT1. Will that be all today?
Great.  That is all.
Ok! Have a great day!
