Domains: train, hotel

user: Hi, I am looking for a hotel to stay in in east cambridge.

assistant: Certainly, there are 6 guesthouses, and one hotel. Do you have any preferences I should include?

user: The hotel in question ideally would be in the expensive price range. It doesn't need to have free parking, though.

assistant: Your best bet would be the Express by Holiday Inn Cambridge. It is an expensive 2-star hotel in the east area of town with free wifi and free parking.

user: If there are not any hotels that do not include free parking then that place will do.

assistant: Great. How many guests should I make a reservation for and what nights would you like to stay?

user: There will be 3 guests for 2 nights starting Sunday.

assistant: I'm sorry, I was unable to book with those constraints, would you like to try another day or a shorter stay?

user: Would it be possible to book this for one night?

assistant: I was able to book one night starting Sunday for 3 guests. Your reference number is 1OOWMJEN . Would you like anything else?

user: Yes, I also need a train to Birmingham New Street.

assistant: I just need some more information. Where are you departing from? What day and what time do you need to leave and arrive by?

user: I would like to depart from cambridge on monday.

assistant: I have 19 available trains. TR6628 leaves at 08:01 and arrives at 10:44. Would you like me to book that for you?

user: Yes please, for the same 3 people. And can I have the reference number?

assistant: I've completed your booking! The reference number for your train is X4WPOS52 . The total cost is 225.3 GBP and is payable at the station. Can I help with anything else?

user: No, that'll be all. Thank you so much for all of your help!
