I want to see local sights, can you help?
Yes, there is a wide variety, do you have an activity type that your are interested in?
I like hiking and seeing historical sites.
I'm sorry, there does not seem to be a historical site or hiking area in Cambridge. Is there anything else I can help with?
Yes, I would like to find a hotel in the cheap price range?
Sure, I can help you with that.  What section of town were you looking for? 
i don't really care about the area.
Okay. Are you interested in hotels that offer internet and/or parking?
Doesn't really matter if they offer either of those or not. I just want it to be a 0 star hotel.

Yes please, 6 people for 5 nights and we would be arriving Monday.

Yes, a guesthouse is fine. I was looking for zero stars and in the cheap price range.
Then the city centre north b and b is what you want, shall I book you?
