Hi, I'm looking for an expensive hotel in the south of town.
The Lensfield hotel should fit your needs perfectly, would you like for me to set up a booking?
Does that hotel have a 3 star rating?
Indeed it does. Does it sound like somewhere you'd like to stay?
I do not need any free parking. Is there any expensive  hotel in the south with 3 stars and no parking?
No, there is not.  The only expensive 3-star hotel in the south is The Lensfield Hotel and it has parking. 
Okay, I need to book it for seven people 5 nights starting tuesday.
I booked it for you. Your reference number is ALYDOZKZ.
Thank you! I also need to book a train to Cambridge.
There are many options. Could you please tell me where you are travelling from, on what day, and possibly at what time?
I need a train going to cambridge that arrives at 11:30. I will depart from kings lynn. 
There are multiple trains that match the criteria you listed. Can you please provide the day you will be traveling on?
I will need that for Tuesday as well.
Train TR1704 leaves kings lynn at 10:11 and arrives at cambridge by 10:58, making the travel time 47 minutes. The cost is 9.80 pounds. Are you interested in booking?
Yes, please book this train for 7 people. I also will need the reference number.
The booking was successful, the total fee is 68.6 GBP payable at the station. Reference number is : JEQ34OF0. Is there anything else I can help you with?
That was it. Thanks so much for your help. 
I'm glad I could help you with your accommodations and travel needs. Good bye.
