I am looking for a guesthouse that has free wifi.
Do you have a price range or specific area?
Area is not important, thanks! 
My favorite guesthouse is the Acorn Guest House, in the north. 4 stars and moderately-priced. Would you like a room there?
That sounds great. I'll need a room for 6 people and 3 nights starting from friday.
Alright! I have made your requested booking and the reference number is P6W6XFMK. Is there anything else I can help you with?
That's all I need for now.  Thanks!
You are very welcome! Have a great day!
Thanks! You too!
Do you need to book anything for travel?
Yes, please, a train from London Liverpool Street to Cambridge.
I have trains departing Cambridge on Friday as early as 05:39 and as late at 23:39. Do you have any preference on what time you'd like to depart by or arrive?
I want to leave after 11:15. If I do, what time do you think I will arrive?
If you leave at 11:39 on train TR7943  you will arrive at 13:07.
Thank you, thats all I need.
