I would like to go and visit Leicester. Do you think you can help me find a train to get me there? 
Sure! There are plenty of trains going to Leicester. What city will you be departing from? 
I will be leaving from cambridge. 
Perfect. What day would you like to travel on? Do you need to depart or arrive by a certain time?
I will be traveling on Sunday and would like to arrive by 08:30 please. 
The first train leaves at 06:21 and arrives at 08:06. How many tickets would you like please?
I need it for eight people, please. 
Great! You're booked on TR9187 with reference number MJJ7J6CV. Is there anything else I can help with?
Yes! I also need to find an expensive guesthouse in the north. It should have plenty of free parking for my fancy car.
I am sorry, there are no expensive guest houses in the north with free parking.  Would you like to try another area?
Then how about one that is in the cheap price range?
There are 2 options. City Centre north has a rating of 0 stars and Worth House has a rating of 4 stars. Would you like me to book either of them?
Worth House sounds good.  Thank you.  
I'll be happy to book a room for you. How many nights and how many people?
I actually just needed the information. That's all I need for now. Thank you. Goodbye.
Sure,thanks for using this service.
