Hi, could you find me a guesthouse that includes wifi?
Sure, what area of town are you interested in?
The area isn't important but we also need free parking.
I have 21 guesthouse. Is there a certain area or pricerange you would prefer?
That one sounds good.  Can I book it for 8 people for 2 nights starting Saturday?
I was able to book acorn guest house, reference number is SM1GU7E5
Thanks. Sound like a great place. Can you help me with a train to peterborough.
What day are you wanting to go? Is there a certain arrival or departure time you're looking for?
I want to leave Cambridge on Monday after 13:15. 
The first train leaving after 13:15 is the TR3066, departing Cambridge at 13:34, arriving Peterborough at 14:24. Would you like to reserve a seat on this train, or keep looking?

I was able to book 8 train tickets for you at the price of 132 GBP, which is payable at the station. The reference number is 66HG2U6U.
Thanks so much. Thats all I need. 
Thank you and have a great trip. Goodbye.
