I am looking for moderately-priced three-star guesthouse in Cambridge.
There are four guesthouses that meet your criteria. Do you need internet or parking?
It doesn't need to have free parking and I don't care about the internet. Which guesthouse can accommodate for 3 people?
I have located one hotel matching your search criteria, the Alpha-Milton Guest House. The phone number is 01223311625. Would you like to make a reservation?
I would like to call them myself please. Thank you. 
Sure. Is there anything else I can help you with today?
Yes please. Can I actually have you book them? I need the reference number as well.
Sure. I will need to know how many people you would like to book it for, what day you would like and how many days you would like to stay.
I'll need the reservation for 3 people starting Saturday for 4 nights.
I have booked your stay at the alpha-milton guest house. The reference number is HS3MWJ10
Thank you, I will also need a train from Peterborough to Cambridge on Saturday. Is there anything available?
There are 38 trains from Peterborough to Cambridge on Saturday, all throughout the day. Can narrow down the time of day you wish to travel?
I wish to arrive before 12:45.
There are 14 trains arriving by that time. When would you like to leave?
Saturday from Peterborough to Cambridge for 3 people. I will need the reference number too please.
Right, Saturday, did you have a time you want to leave by? The trains leave every 30 minutes starting at 5:19
It doesn't matter when I leave, as long as I arrive by 12:45. 
TR5538 leaves at 11:48 and will arrive by 12:38. Would you like for me to book this train for you?
Yes, for the same group of 3 people from before.
Your booking was successful. Reference number is PR8JE3DU and total is 39.59 GBP. Can I help you with anything else today?
No I think that will be it, thank you for your help!
You're welcome. Enjoy your time in Cambridge!
