I am looking for a moderately priced hotel that has free wifi.
No problem. We have 17 such candidates. Do you want to specify further?
I am looking for a hotel in the west and it doesn't need to have free parking.
There are no hotels in the west, moderately priced with internet. Would you like to braoden your search?
Let's try for one in the north area instead.
The only thing available in the north is a guesthouse with the internet moderately priced with 4 stars. 
That's fine. I would like to book it for 3 people for 5 nights starting on Tuesday.
I appreciate your help. Thank you
What was the name of the hotel please?
There actually is a moderately priced place in the west with free wi-fi. It is a guesthouse called Hobson's House. Would you like me to make a booking for you?

The booking was unsuccessful. May I book you for another day or a shorter stay?
how about for 3 days?
Yes, indeed! I can make a booking for three people for three days. The reference number for that booking is 463S05XE.
Thank you very much! Can you also help me find a train? I am looking for one that leaves from Cambridge after 11:00 and goes to Kings Lynn on Friday.
There are 13 possibilities. Every ride is 47 minutes and the cost is the same. Is there a certain time you'd like to arrive?
I'll take the train that is closet to 11:00 please. 
There is one leaving at 11:11. How many tickets do you need?
I need tickets for 3 people.
Booking was successful, the total fee is 29.4 GBP payable at the station. Reference number is : RQ12EQA0.
Thank you! That's everything I needed. Have a great day!
You're welcome, have a nice day.
