I'm visiting Cambridge as a tourist!  I'm looking for an expensive place to stay that includes free parking!
I've got 5 expensive hotels with free parking. Do you care what part of the city you stay in? If not, I'd recommend University Arms Hotel.
The only other preferences I have are that the hotel is a guesthouse with free wifi.
There are no guestrooms that meet your requirements.  Would you be interested in a hotel room?
Is there a hotel in a more moderate price range with fee wifi?
I found Arbury Lodge Guesthouse that I think will fit your needs. It is moderately priced, four stars and includes parking and internet! 
What area is the Arbury Lodge in?
The Arbury Lodge guesthouse is located in the northern part of town. 
OK, I'll look into that one. Can you also tell me about the museums in town?
We have 23 museums, I'd recommend Byard Art if you are interested in art.
Is there an entrance fee for Byard Art?
No, no fee to get into byard art. Can I help with anything else?
That's all. Thank you! Bye!
Okay, glad I could be of help.
