I need a train leaving broxbourne on wednesday.  Can you book it for me?
Sure! What is your destination?
I need to arrive in Cambridge by 11:45.
I have train TR1819 that leaves at 10:32 and arrives in Cambridge at 11:32. Would that work for you? 
yeah, what's the price of the tickets?
The price of the tickets is 17.90 pounds. Shall I make a booking for you?
Yes, please. I'm also looking for a hotel that's cheap and in the north. 
There are no cheap hotels in the north but there are 2 guesthouses. Will those work?
That sounds fine.
Which one would you be interested in? I recommend Worth House because it is 4 stars.
Actually, can you try a moderate price hotel in the north instead?  Sorry for the trouble.
We have 11 options that meet your criteria. Would you like to narrow it down by stars, internet, or parking?
Yeah, I don't need internet. Other than that, could you just recoomend one that has a reasonable number of stars?
How about the alpha-milton guest house?  It's in the north and moderately priced.
that will be fine. book it for me
How many people and for how many nights?
book it for 2 people and 5 nights starting from the same day.
