I'm looking for a train that departs cambridge on saturday.  Any ideas?
There are 202 trains that leave Cambridge on Saturday.
I would like to leave after 16:30 and would like to go to kings lynn. 
There are 7 trips that would work. The earliest leaves at 17:11 and the latest leaves at 23:11. The train ride will be 47 minutes. What would you prefer?
I'm interested in the earliest one. What is the train ID? 
That's the TR2840.
Alright, are there any 1 star hotels that offer free parking?
I am not showing any hotels with 1 star that have free parking, would you like to look for something else?
Does any of them have free wifi?
Sorry, no, I do not see any one star hotels with free wifi. Would you like to try another option?
Are there any with 4 stars?
We have three 4 star hotels that provide free internet and free parking.  Is there an area you would prefer to stay at?
Any place is fine, I go with whatever you recommend.
I recommend The Cambridge Belfry, a cheap 4-star hotel on the west side. Would you like to reserve a room? 
Yes please and I'll also need the postcode.
I need more information on the number of nights and people. 
I need the postcode, hotel type, and price range for The Cambridge Belfry.
the postcode is cb236bw. it is a hotel in the cheap price range. when would you like to stay from, how many people, and for how long?
Forget about booking it, just please tell me what type of hotel it is.
The cambridge belfry is a hotel, not a guesthouse. May I help  with something else?
That was all I needed.  Thank you.
You're welcome! Have a great day.
