I'm trying to take a train from bishops stortford to cambridge
Okay great, there are plenty of options for you. Did you have a certain day and time in mind for departure?
I want to leave on monday after 18:30.
There is a train that leaves at 19:29, would you like to book it?
What is the arrival time? I also need the train ID and price.
Your arrival time is 20:07 on train TR5806. Total price is 10.10 pounds. Would you like me to book a ticket?
No that won't be necessary. I would like to find a place to stay though, and I'll need free parking. 
Indeed, we have many options with free parking. Would you prefer a guesthouse or a hotel?
Well, I need a place in the south with a 4-star rating, but either hotel or guesthouse is OK.
aylesbray lodge guest house is in the moderate price range and rosa's bed and breakfast is in the cheap price range.  Which do you prefer?
Can you send me the hotel type and postcode and whether they have internet?
Both have internet and are guesthouses. Aylesbray lodge's postcode is cb17sr. Rosa's postcode is cb22ha. 
Great, thanks! That's all I needed.
