I need a train departing from cambridge and arriving by 20:45.
What day are you traveling, and to which station?
I'll be traveling on wednesday, and I will be go to peterborough. 
We have 30 such entries. Do you have a time you'd like to leave by?
Any time is fine as long as I can book for four people. I also need the reference number, please.
Alright. I booked your train leaving Cambridge at 19:34 and arriving in Peterborough at  20:24. The reference number is A8T38EJZ. 
Thanks. I'm also looking for a hotel (not a guesthouse) with free wifi.
There are 9 different hotels that have free wifi that aren't guesthouses, do you have a price range in mind?
No particular price range but I would like it to be in the centre.
Cityroomz is a moderately priced hotel with internet. Would that work for you?
Yes that will work. Can I get the hotel's phone number?
Sure thing, their number is 01223304050. Is there anything else I can help you with today?
No, that will be all, thank you for your help!
Okay. Call us back if you need me to book anything for you.
Thanks, have a good day.
You, too. Goodbye.
