Domains: train, hotel

user: Hi, I would like to purchase a train ticket.

assistant: I can help you with that. Where would you like to arrive and depart from and on what day?

user: I want to depart from london liverpool street on Saturday leaving after 08:30 to go to cambridge

assistant: TR0357 will leave at 09:39, would that work for you?

user: That sounds like it will work. Can you book 7 seats for us? I'll need a reference number.

assistant: 7 seats have been booked and your reference number is: MN2WKAWI

user: I also need to find a place to stay while there. Preferably something expensive.

assistant: ok there are 5 different ones. Which area of town are you wanting to stay in?

user: I'm flexible on the area but I really want a hotel instead of a guesthouse. And I would like something with 4 stars.

assistant: You have two choices that match your criteria: Huntingdon Marriott Hotel in the west, and University Arms Hotel in centre. Would you like to book a room at one of these?

user: Do either of them have free parking?

assistant: Yes, both of them. Is there anything else about them you'd like to know?

user: I would like to book one of those for 2 nights please.

assistant: OK, how many people will be staying and what day will you be checking in?

user: 7 people on the same night.

assistant: Booking was unsuccessful at both hotels. Would you like to change the duration of your stay?

user: Sure, try just 1 night.

assistant: Booking was successful at the University Arms Hotel located in the centre of town. They are 4-star rated and have free parking and wifi. Reference number is: 5Y7U9B9A . Is that ok?

user: Yeah that works for me. It's also all I needed for today. Thanks!

assistant: Thank you for using our service. Have a great evening. Goodbye.
