I'm looking to stay at a moderate priced place with free parking.
Both the Ashley Hotel and the Lovell Lodge fit that bill.  They are both pretty similar, do you have any preference?
Do either of them have a star rating of 4?
No, both of those hotels have 2 star ratings and are located in the north part of town. Do you want a 4 star hotel somewhere else?
I would like a 4 star hotel that is priced moderatly. I don't have preference in the part of town. 
I have 9 available but there are no hotels, only guesthouses. Is that okay? 
A guesthouse would be fine.
Okay, for how many people how long and when please?
I need to book for 3 people on 3 nights starting tuesday.
The booking for Acorn Guesthouse was successful. The reference number is A3J9JE6H. 
Are there any colleges in town? I want to see some.
Education is a core of industry in cambridge, we have 18 college, any preference by area?
No area preference. I would appreciate a recommendation. 
i recommend corpus christi. it is in the centre
Ok that sounds good. Could you tell me what the entrance fee is there?
no fee's it is free admission
Perfect, that takes care of me, thanks for your help.
Have a nice day.
