I am looking for a place to stay. The hotel should have a star of 4 and should include free wifi
Try the a and b guest house or arbury lodge guesthouse
Are either of those in the cheap price range?
In what section of town are you looking to stay? I have 8 different lodgings that fit your requirements.
I am not really picky.
I would like the arbury lodge guesthouse  
Is it cheap?
No, but the alexander bed and breakfast is in the cheap range and has wifi. It's in the centre of town. Would you like me to reserve a room for you?
That sounds good, yes. I need 4 nights booked for me, beginning Friday and for 7 people. 
I'm sorry. Alexander bed and breakfast is fully booked. Do you want to book starting another day or for a shorter stay?
Yes, 3 nights please and can I have a reference number
I've booked that reservation. The reference number is 1G6A07OI. Can I assist with something else?
No, I've got everything I need. I appreciate your help.
Great, thank you for using Cambridge TownInfo centre. Goodbye!
