Task-oriented dialogue about: train
hotel

I need to book a hotel in the east that has 4 stars.
I can help you with that. What is your price range?
That doesn't matter as long as it has free wifi and parking.
If you'd like something cheap, I recommend the Allenbell. For something moderately priced, I would recommend the Warkworth House.
Could you book the Wartworth for one night, 1 person?
What day will you be staying?
Friday and Can you book it for me and get a reference number ?
Booking was successful. Reference number is : BMUKPTG6 . Can I help you with anything else today?
I am looking to book a train that is leaving from Cambridge to Bishops Stortford on Friday.
There are a number of trains leaving throughout the day. What time would you like to travel?
I want to get there by 19:45 at the latest.
Okay! The latest train you can take leaves at 17:29, and arrives by 18:07. Would you like for me to book that for you?
Yes please. I also need the travel time, departure time, and price.
Reference number is : UIFV8FAS . The price is 10.1 GBP and the trip will take about 38 minutes. May I be of any other assistance?
Yes. Sorry, but suddenly my plans changed. Can you change the Wartworth booking to Monday for 3 people and 4 nights?
I have made that change and your reference number is YF86GE4J
Thank you very much, goodbye.
You're welcome. Have a nice day!
