I'm looking for a 4 star hotel, and it doesn't need to have free parking.
I have three hotels that meet your criteria. Are you looking for a specific part of town? 
No, but price is important- anything moderately priced on your list?
I have a cheap 4 star in west, and two expensive ones - one in west and one centre. Which one are you interested in? 
I'd like a hotel that is in the moderate price range.  Could you recommend that for me?
I'm sorry, but I don't have any hotels in the moderate price range that are 4 stars. If you're interested in a guesthouse, though, we do have options for you.
What are those options?
You could try the allenbell.
All right, let's try that. May I get a reservation for Friday and Saturday night, 8 people each night?
Thank you for waiting.  Your reservation has been made.  Your reference number is G9EWB5NN.  Is there anything else I can help you with?
I also need a train on Sunday from Cambridge to Peterborough leaving after 14:15.
Is there a time you need to arrive by?
No, I just need to leave after 14:15 please. 
Okay the TR3577 leaves at 14:34. 
Great, thanks so much! That's all I need! Have a great day!
You too, enjoy your stay.
