I am looking for a place to stay that has a 4 star rating in the east part of town.
I have 6 places that would fit your needs. Do you have a specific price range in mind?
A cheap one with wifi, please. 
I think allenbell would fit your needs. Would you like a reservation?
Yes a booking for 8 people for 3 nights starting on Tuesday.
Unfortunately there isn't any availability during that time. Would you like to book another day or shorten your stay?
No, I would need it to be for 3 days and 8 people, what hotel could accomidate me?
I am sorry there are no hotels available.  Would you like another type of lodging? 
Actually, could you shorten that to one night?
There is one hotel available, Express by Holiday Inn Cambridge, however it is only 2 stars and in the expensive range.
Please, book the Holiday Inn Cambridge, and I need the reference number. Also, I am looking to book a train the same day from Birmingham new street  to Cambridge leaving after 18:30.
I apologize, the hotel booking was unsuccesful. Would you like to try another day?
Can you try the hotel with a 1 night stay on the same day?
You are in luck for 1 night at Allenbell.  The reference number is PYGL9EVW.  You would like a train?
Yes, I need a train from birmingham new street to cambridge.
On Friday there are a train leaving at 5:40 and the cost is 75.10 pounds. The trains depart every hour, so you can chose your time. The last train depart at 9:40.
I want it to leave after 18:30. 
Is there a time you need to arrive by?
No, but I would like to know the arrival time for the train fitting my criteria. 
TR8903 leaves Birmingham New Street at 18:40 and arrives in Cambridge at 21:23. It's a rather long trip.
Thank you for your assistance.
Is there anything else that I can help you with?
No, that will be all. Thank you so much! Have a good day.
Great, we hope you have a great stay.
